C Program to Add Two Distances (in inch-feet) System Using Structures
This program takes two distances (in inch-feet system), adds them and displays the result on the screen.
#include <stdio.h>
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);
sumOfDistances.feet = d1.feet+d2.feet;
sumOfDistances.inch = d1.inch+d2.inch;
// If inch is greater than 12, changing it to feet.
if (sumOfDistances.inch>12.0)
{
sumOfDistances.inch = sumOfDistances.inch-12.0;
++sumOfDistances.feet;
}
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 (a float) and feet (an integer).
Two variables (d1 and d2) are created which stores two distances (in inch and feet). Then, the sum of two distances is stored in sumOfDistances structure and displayed on the screen.
First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.
After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
