Example of Total & Average(where n is fixed) & Unsigned int

#include <stdio.h>
#include <stdlib.h>

int main()
{
    unsigned int bangla_number, english_number, math_number, total, average;

    // Enter Bangla Number
    printf("Enter Your Bangla Number\t:");
    scanf("%d", &bangla_number); // &operator is not used for string but used for all scanf() so here I used & sign before operator

    // Enter English Number
    printf("Enter Your English Number\t:");
    scanf("%d", &english_number);

    // Enter Math Number
    printf("Enter Your Math Number\t\t:");
    scanf("%d", &math_number);

    // Calculation
    // unsigned int total = (bangla_number+english_number+math_number); --->> can't use this code because variable must be declare first on the top
    total = (bangla_number+english_number+math_number);
    average = (total/3);

    //printf("You've got %d in your Bangla exam.", bangla_number);
    // Print
    printf("You've got total %d marks in your exam and your average number is %d.", total, average);
    return 0;
