Strings

Q1:

What will be the output of the program ? 
#include<stdio.h>

int main()
{
    char str[] = "Nagpur";
    str[0]='K';
    printf("%s, ", str);
    str = "Kanpur";
    printf("%s", str+1);
    return 0;
}

A Kagpur, Kanpur

B Nagpur, Kanpur

C Kagpur, anpur

D Error

ANS:D - Error

The statement str = "Kanpur"; generates the LVALUE required error. We have to use strcpy function to copy a string. To remove error we have to change this statement str = "Kanpur"; to strcpy(str, "Kanpur"); The program prints the string "anpur"
