Loop forever

[Will2k]

I am trying to make this function keep going on until I call an interrupt or, delete function in my GCC. HEre is what I have. I tried putting a while(1) loop in my driver.c but it does not stop.

#include <stdio.h>
 
int sreplace(char newc, char oldc, char *s)
{
 
        int cnt;
        cnt = 0;
 
        while(*s !='\0') //loop to run till the end of the string
        {
                if(*s == oldc) //if the char found which to be replaced
                {
                        *s = newc; //replace
 
                        cnt++;
                }
                s++;
 
        }
        return cnt;
}
 
 

#include <stdio.h>
 
char *strmatch(char *str, char *s)
{
 
 
        char *tmp;
 
        while(*str!='\0'){
                tmp = s;
                while(*tmp !='\0' && *str == *tmp)
                {
                        str++;
                        tmp++;
                }
                 if(*tmp =='\0')
                 {
                        return str;
                 }
 
        str++;
        }
        return(NULL);
}
 
 

#include <stdio.h>
int sreplace(char newc, char oldc, char *s);
char *strmatch(char *str, char *s);
 
int main()
{
        char line1[1024];
        char line2[1024];
        char *ptr;
        char *s1, *s2;
 
 
        fgets((s1=line1),1024,stdin);
        fgets((s2=line2),1024,stdin);
 
         sreplace('\0','\n', line1);
         sreplace('\0','\n', line2);
 
        ptr = strmatch(s1,s2);
 
        printf("%s\n",ptr);
 
 
        return 0;
 
}

Hi.

If you want to have a forever loop, try this:

while(1)
{

code block;

//loop control goes here:
if(test method)
break;
}

This break; statement would let you terminate the while loop.

or you could put the test method in the while condition...
