Thread: string help needed

I am a newbie and just learning about strings. I am trying to create a program that accepts a floating point, an integer,and a character.
The program must have a call function that assembles the input data into a string. It must display the assembled string using puts() call back after the main function has completed. Here's what I have, but Have the following errors and cannot figure it out. Any help is greatly appreciated.

Code:

 

#include <stdio.h>
void combine (char *, int, float*);
int main()
{
char strng1[80],strng2[100];
int num, char*,float*;
printf("enter a string:");
gets(strng1);
printf("enter an integer number:");
scanf("%d", &num);
printf("enter a character:");
scanf("%c", &char*);
printf("enter a floating point:");
scanf("%f",&float*);
combine (strng1, strng2, int, float*,char*);
printf("A string containing all inputs is:");
puts(strng2);
return 0;
}
void combine(char*source,char *dest, int,float*)
{
sprintf(dest,"%c%d%1f",source, float*);
return;
}

I am still geeting the following errors even when I change the int num, char* and Float*

What have you exactly changed?? It seems to me you are starting to learn c language as well. char and float are reserved keywords of the language.
Try something like

Code:

#include <stdio.h>
#include <string.h> /* string utilities */

int
main()
{
int num;
char c;
float floatNum;
 
/* YOUR CODE HERE but make sure you use the correct variables */

return 0;
}

Have a look on sprintf() as well.

still getting 3 errors with parameters ( combine) and function header and & errors!! please help

Code:

#include <stdio.h>
#include <string.h>
void combine (char c, int num, floatnum);
int main()
{
char strng1[80],strng2[100];
int num;
char c;
floatnum;
printf("enter a string:");
gets(strng1);
printf("enter an integer number:");
scanf("%d", &num);
printf("enter a character:");
scanf("%c", &c);
printf("enter a floating point:");
scanf("%f",&floatnum);
combine (strng1, strng2, &num, floatnum, &c );
printf("A string containing all inputs is:");
puts(strng2);
return 0;
}
void combine(char c,char *dest, int num,floatnum)
{
sprintf(dest,"%c%d%1f",source, floatnum);
return 0;
}

No, I guess it has something to do with the combine statement and the different variables, but I am not sure

First, you have this.

Code:

char strng1[80],strng2[100];
int num;
char c;
floatnum;

We'll just ignore the whole gets thing right now, but go read the FAQ on it anyway...

Code:

combine (strng1, strng2, &num, floatnum, &c );

You call that, which is FIVE arguments. Look up above again.

Code:

void combine(char c,char *dest, int num,floatnum)

Finally, you have that, which is FOUR arguments. You sure you can't figure out what's wrong yet?

I know it has something to do with the combine variables, but I am not sure what is rt.
