C percentage program

Here is an example of a C program that calculates the percentage:

#include <stdio.h>

int main() {
    float obtained_marks, total_marks, percentage;

    printf("Enter obtained marks: ");
    scanf("%f", &obtained_marks);

    printf("Enter total marks: ");
    scanf("%f", &total_marks);

    percentage = (obtained_marks / total_marks) * 100;

    printf("Percentage: %.2f%%\n", percentage);

    return 0;
}

This program prompts the user to enter the obtained marks and total marks, calculates the percentage using the formula (obtained_marks / total_marks) * 100, and then prints the result.
