Write a program in C that reads a firstname, lastname and year of birth and display the names and the year one after another sequentially.

Pictorial Presentation:

C Input Output: Display firstname, lastname and year of birth sequentially

Sample Solution:

C Code:

#include <stdio.h>
int main()
{
    char firstname[20], lastname[20];
    int bir_year;
    printf("Input your firstname: ");
    scanf("%s", firstname);
    printf("Input your lastname: ");
    scanf("%s", lastname);
    printf("Input your year of birth: ");
    scanf("%d", &bir_year);
    printf("%s %s %d\n", firstname, lastname, bir_year);
    return 0;
}

Sample Output:

Input your firstname: Tom

C Programming: Tips of the Day

Static variable inside of a function in C

The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().

The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.

The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
