C Program to Add Two Distances (in inch-feet system) using Structures

In this example, you will learn to take two distances (in the inch-feet system), add them and display the result on the screen.

To understand this example, you should have the knowledge of the following C programming topics:

Program to add two distances in inch-feet system

struct Distance {
    int feet;
    float inch;
} d1, d2, sumOfDistances;

int main() {
    printf("Enter information for 1st distance\n");
    printf("Enter feet: ");
    scanf("%d", &d1.feet);
    printf("Enter inch: ");
    scanf("%f", &d1.inch);
    printf("\nEnter information for 2nd distance\n");
    printf("Enter feet: ");
    scanf("%d", &d2.feet);
    printf("Enter inch: ");
    scanf("%f", &d2.inch);

    // If inch is greater than 12, changing it to feet.
    if (sumOfDistances.inch>12.0) {
        sumOfDistances.inch = sumOfDistances.inch-12.0;
    printf("\nSum of distances = %d\'-%.1f\"", sumOfDistances.feet, sumOfDistances.inch);
    return 0;


Enter information for 1st distance
Enter feet: 23
Enter inch: 8.6

Enter information for 2nd distance
Enter feet: 34
Enter inch: 2.4

Sum of distances = 57'-11.0"

In this program, a structure Distance is defined. The structure has two members inch (float) and feet (integer).

Two variables (d1 and d2) are created which stores two distances (in inch and feet). Then, the sum of the two distances is stored in sumOfDistances and displayed on the screen.
