C program - Convert Feet to Inches

Let's consider the following example:

#include<stdio.h>

int main()
{
		int feet,inches;
		
		printf("Enter the value of feet: ");
		scanf("%d",&feet);
		
		//converting into inches
		inches=feet*12;
		
		printf("Total inches will be: %d\n",inches);
		return 0;
}

Output

    Enter the value of feet: 15 
    Total inches will be: 180

Using user define function

Here we are going to declare an user define function feet2Inches() this function will take feet as arguments and returns inches value.

#include<stdio.h>

//function feet2Inches
int feet2Inches(int f)
{
	return (f*12);
}

int main()
{
		int feet,inches;
		
		printf("Enter the value of feet: ");
		scanf("%d",&feet);
		
		//converting into inches
		inches=feet2Inches(feet);
		
		printf("Total inches will be: %d\n",inches);
		return 0;
}

Output

    Enter the value of feet: 15 
    Total inches will be: 180
