#include<stdio.h>

int main()
{
char a[20],b[20];
int l1,l2,i=0,j=0;
printf("\nEntert the first string ");
while((a[i++]=getchar())!='\n');
l1=i-1;
printf("\nEnter the second string ");
while((b[j++]=getchar())!='\n');
l2=j-1;
if(l1>l2)
{
printf("\nThe first string is greater than the
second ");
}
else if(l2>l1)
{
printf("\n Second string is greater than the first ");
}
else
{
printf("\nBoth the strings are equal ");
}
getch();
}

Answer / bin

Here is a subroutine that does strcpy, returns 0 if both are equal, returns a positive number, if arg1 is higher else returns a negative number


int mystrcmp(char *s1, char *s2)
{
while (*s1 != 0 && *s2 != 0 && *s1 == *s2) {
++s1; ++s2;
}
return (*s1) - (*s2);
}

main() { int a,b; printf("%d,%d",scanf("%d%d",&a,&b)); } => do u mean above program's output... =>output will be:2,whatever you enter value for b. =>because scanf is a library fn which will return how many arguements it processes, and second value you are right mr.Satya but i found my self unable to understand that for the first time scanf returns the no of successful matches but how for the second time it returns the value of 'b'.while a function should return the same 'r' value every time.
