C Exercises: Calculate average consumption from the given total distance and fuel spent

C Basic Declarations and Expressions: Exercise-14 with Solution

Write a C program to calculate a bike’s average consumption from the given total distance (integer value) traveled (in km) and spent fuel (in liters, float number – 2 decimal point).

C Code:

#include <stdio.h>
int main() 
{
	int x;
	float y;
	printf("Input total distance in km: ");
	scanf("%d",&x);
	printf("Input total fuel spent in liters: ");
	scanf("%f", &y);
	printf("Average consumption (km/lt) %.3f ",x/y);
	printf("\n");
	return 0;
}

Sample Output:

Input total distance in km: 350                                        
Input total fuel spent in liters: 5                                    
Average consumption (km/lt) 70.000

C Programming: Tips of the Day

Static variable inside of a function in C

The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().

The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.

The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
