printf("enter string 2: ");
scanf("%s",b);
str(a,b); printf("%s",z);
}
void str(char *x,char *y) {
int i=0,leny=0,count=0;
char *p;
p=y;
while(*y!='\0')
{
leny++; y++;
}
while(*x!='\0')
{
y=p;
while(*y!='\0')
{
if(*x!=*y)
{
y++; count++;
}
else
{
break;
}
if(count==(leny+1))
{
z[I]=*x;[/I]
[I] i++; [/I]
[I]break;[/I]
[I] }[/I]

    You are modifying variable 'z' inside the function str(). That is a local variable which is visible only inside that function. Whatever changes you make to that variable will not be reflected in the variable 'z' used in main. If you want to store the remaining characters in another variable, you should pass that variable also as a parameter to the function. ie., declare z as a character pointer in main, and pass z as an additional parameter to str()

    k..i did what u said...n nw the code is..
    #include <stdio.h>
    #include <stdlib.h>
    void str(char *a,char *b,char *c);

    int main()
    {
    char a[15];
    char b[15];
    char z[15];
    printf("enter string 1: ");
    scanf("%s",a);
    printf("enter string 2: ");
    scanf("%s",b);
    str(a,b,z);
    printf("%s",z);

    }
    void str(char *x,char *y,char *z)
    {
    int i=0,leny=0,count;
    char *p;
    p=y;
    while(*y!='\0')
    {
    leny++;
    y++;

    }
    while(*x!='\0')
    {

    y=p;
    count=0;

    while(*y!='\0')
    {
    if(*x!=*y)
    {
    y++;
    count++;
    }
    else
    {

    break;

    }
    if(count==(leny))
    {
    *z=*x;
    z++;
    break;
    }
    }
    x++;

    }
    }



    but still its not giving the correct output.... 😔
