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

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

If you do not know, 12 inches is 1 foot.

## Program to add two distances in the inch-feet system

``````#include <stdio.h>

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

int main() {
// take first distance input
printf("Enter 1st distance\n");
printf("Enter feet: ");
scanf("%d", &d1.feet);
printf("Enter inch: ");
scanf("%f", &d1.inch);

// take second distance input
printf("\nEnter 2nd distance\n");
printf("Enter feet: ");
scanf("%d", &d2.feet);
printf("Enter inch: ");
scanf("%f", &d2.inch);

result.feet = d1.feet + d2.feet;
result.inch = d1.inch + d2.inch;

// convert inches to feet if greater than 12
while (result.inch >= 12.0) {
result.inch = result.inch - 12.0;
++result.feet;
}
printf("\nSum of distances = %d\'-%.1f\"", result.feet, result.inch);
return 0;
}``````

Output

```Enter 1st distance
Enter feet: 23
Enter inch: 8.6

Enter 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:

• feet - an integer
• inch - a float

Two variables d1 and d2 of type `struct Distance` are created. These variables store distances in the feet and inches.

Then, the sum of these two distances are computed and stored in the `result` variable. Finally, result is printed on the screen.
