What will be the output of the following C program?#include<stdio.h>int main(){    char str[] = "Nagpur";    str[0]='K';    printf("%s, ", str);    str = "Kanpur";    printf("%s", str+1);    return 0;}Select one:Nagpur, KanpurErrorKagpur, KanpurKagpur, anpur

The output of the given C program will be an error.

Here's the step by step explanation:

1. The program starts with including the standard input-output library using #include<stdio.h>.

2. The main() function is declared which is the entry point of the program.

3. Inside the main() function, a character array str[] is declared and initialized with the string "Nagpur".

4. The first character of the string, str[0], is then changed from 'N' to 'K', making the string "Kagpur".

5. The program then prints this modified string using printf("%s, ", str);, so "Kagpur, " is printed.

6. The next line str = "Kanpur"; attempts to change the entire string from "Kagpur" to "Kanpur". However, in C, you cannot change the entire string stored in a character array like this after it has been declared. This line will cause a compilation error.

So, the correct answer is: Error.
