Thread: Please Help (capitalise sentences)

I am trying to read characters from output and converting the first letter of the character to capital case and ignore or delete space when ever i see '\0' or leave the space if the next character is in upper case ..please i need a clue on what to do ...i have already begin but i need help cuz i am confused now.

Code:

#include <ctype.h>
#include <stdio.h>
#include <stdlib.h>

#define UPPER_CASE 1
#define LOWER_CASE 2

int main(void) {

    int c;
    while ((c = getchar()) != '\n') {
            
         if ( isalpha ( c) ) 
		 	{
         	
  		 if ( islower  ( c ) )
		   	 {
  		 	
      		c = toupper( c );
		  
			  putchar(c);
		   
  		 }
         }
         
          
    }
    return EXIT_SUCCESS;
}

Thanks for your reply....i have thought of that but my problem how do i read when the first letter has gone in and after reading that do i have to putchar and start reading for another letter ...please help me understand iit better.

Code:

#include <stdlib.h>

#define UPPER_CASE 1
#define LOWER_CASE 2

int main(void) 
{

    char c;
	int i=0; //flag to check if first character
	while(c!='\n')
	{
   	c = getchar(); 
            
         if (isalpha(c)) 
		 {
          if ( islower  (c) )
		   	{
  		 	if(i==0)
			{
      		c = toupper(c);
			i++;	
			}
		    putchar(c);
		    }
			else
			if(isupper(c)) //checking if caps
			printf(" %c",c);//if caps,print a space and then the char
         }
         
        
    }
    return EXIT_SUCCESS;
}

im just a beginner so completely following the above code might not be good as coding practice might not be so good.
when i run your code, i get an access violation error .i don't know why.

the above code does what you want.

i made the following modifications:
1>a flag variable i :to check if the character being read is the first character.
2>if there is a caps character,then print a space and the character.

hope this is what you want.

I was able to come up with this ...i don,t really know how to put a space in the while loop ......I want to put a space after the first character..

Code:

#include <ctype.h>
#include <stdio.h>
#include <stdlib.h>



int main(void) {
    int last_digit_seen = 0;
    
    int c;
    while ((c = getchar()) != '\n') {
        if (!isalnum(c))
            continue;
        if(last_digit_seen==0 && (islower(c)))
            {
             c=toupper(c);
			
            }
            putchar(c);
            
        
    }
    putchar('\n');
    return EXIT_SUCCESS;
}

your question is not so clear.

im assuming that if you give input as abcd
then your o/p should be: A bcd
is this what you want?

so your problem is that if you put a space inside the while loop,it will get printed again and again. but you want only a single space.
if this is what you want,confirm in your next post.

if you want a space after the first character only,then use a flag variable as below:

Code:

#include <ctype.h>
#include <stdio.h>
#include <stdlib.h>



int main(void) {
    int last_digit_seen = 0;
    
    int c;
    int i=0; //flag variable
    while ((c = getchar()) != '\n') {
        if (!isalnum(c))
            continue;
        if(last_digit_seen==0 && (islower(c)))
            {
             c=toupper(c);
			
            }
            if(i==0)
            {
            printf(" ");  // prints a space in the first run
             i++;// increment so that in the next looping,no space wont be printed as the 
                  if condition would go wrong.
            }
            putchar(c);
            
        
    }
    putchar('\n');
    return EXIT_SUCCESS;
}

yes ..Thats what i want ...after runing the code, the first letter appears two place ....ie in the first place and after the space .

Code:

 if(i==0)
            {
            printf(" ");  // prints a space in the first run
             i++;// increment so that in the next looping,no space wont be printed as the 
                  if condition would go wrong.
            }
            putchar(c);

Code:

#include <ctype.h>
#include <stdio.h>
#include <stdlib.h>

#define UPPER_CASE 1
#define LOWER_CASE 2

int main(void) {
    int last_digit_seen = 0;
    int i=0;
    int c;
    while ((c = getchar()) != '\n') {
        if (!isalnum(c))
        {
        	continue;
        }
        
        if(last_digit_seen==0)
            {
             c=toupper(c);
  		    	putchar(c);
  		        ++last_digit_seen;	
            }
            
             if(last_digit_seen==1)
            {
            printf(" ");  
             ++last_digit_seen;
            }
            putchar(c);

    }
    return EXIT_SUCCESS;
}

really sorry about that last post dude.that program wont give you the correct output.
just make the following changes:

Code:

  if(i==0)
            {
            printf("%c ",c);  
             i++;
            }
		else
            putchar(c);

now a space will be printed after the first character.
but now all characters are printed in caps. is that what you want?

just give me a sample input and sample output that would make your need clear.

are you saying this to me or to code_lover?

I want some thing like this ...when you input the first , it will output thse second.


Only letters and spaces are output, other symbols such as ^ are ignored.

ok that needs some thinking. let me try to figure out.
hope some veteran comes here soon.

meanwhile,keep trying.if you get the code,dont forget to post!

right now ...i have come up with this ....

Code:

#include <ctype.h>
#include <stdio.h>
#include <stdlib.h>

#define UPPER_CASE 1
#define LOWER_CASE 2

int main(void) {
    int last_digit_seen = 0;
    int c;
    while ((c = getchar()) != '\n') {
        if (!isalnum(c))
            continue;
        
        if(last_digit_seen==0)
            c=toupper(c);
	     	 putchar(c);
           last_digit_seen++;
        if(last_digit_seen==1)
            printf("%c",'\0');
            last_digit_seen++;
            
            c=getchar();
			putchar(c);
		if(last_digit_seen >1)
		 ;
		  	/* i need to append the characters together ....*/
    }

    putchar('\n');
    return EXIT_SUCCESS;
}
