Thread: lower to upper

This is a program that prints 5 user inputs of characters. I want to change the user input to upper case using toupper. I have tryied to place the function in all possible lines but it does not work

I also want to print the output in 2 columns....how can i do that??

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

int main (void)
{
int k,cnt;
char line[81];
char *t[5];

for (k=0; k<5; k++)
{
gets(line);
if feof(stdin) break;
t[k]=(char*) malloc(1+strlen(line));
if (t[k]==NULL)
{
printf("out of storage");
break;
}
strcpy(t[k], line);
}

cnt=k;
printf("count=%d\n",cnt);

for (k=0; k<cnt; k++)
{
printf("%d %s\n", k,t[k]);
free(t[k]);
}
return 0;
}

for ( i = 0 ; i < strlen(line) ; i++ ) line[i] = toupper( line[i] );

but where do i put it in my program???

That's my problem!!!

Somewhere between reading the line in, and printing it out

> strcpy(t[k], line);
It really doesn't matter whether its before or after this (for example) - either will work and both are equally valid solutions

I put it after strcpy....

but it still print in lower case!!!!

Here are my latest codes:


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

int main (void)
{
int k,i,cnt;
char line[81];
char *t[5];

for (k=0; k<5; k++)
{
gets(line);
if feof(stdin) break;
t[k]=(char*) malloc(1+strlen(line));
if (t[k]==NULL)
{
printf("out of storage");
break;
}
strcpy(t[k], line);

for(i=0;i<strlen(line);i++) //<<<============
line[i]=toupper(line[i]);
}

cnt=k;
printf("count=%d\n",cnt);

for (k=0; k<cnt; k++)
{
printf("%d %s\n", k,t[k]);
free(t[k]);
}
return 0;
}

mmm - try before then

I think maybe the problem is that the second for loop is nested inside the first...so you are toupper()ing each char and then you are replacing it with another line read from gets()...or something like that.

PHP Code:

void capitalize (char input[20])
{
    int i;
    for (i=0; input[i]; i++)
    {
        if (input[i]>='a' && input[i]<='z')
        {
            input[i]=input[i]-32;
        }
    }

} 


by standard, do you mean using "toupper" ?
are people still using EBCDIC ?

how do we know which functions are standard and which are not ? 'cause i want to write code that runs on most compilers (if not all of them)
i can't compile some programs in unix (gcc). it compiles
well with borland/turbo c++, etc..
