Question

In 80X86 assembly language

Calories Burned
Running on a particular treadmill, you burn 4 calories per minute. Write a program that uses a loop to display the number of calories burned after 5, 10, 15, 20, 25, and 30 minutes

pls show input and output

Answer 1

C code :

#include <stdio.h>

int main()
{
const float CALORIES_BURNED_PER_MIN = 3.6;

float calories_burned = 0;

for (int i = 5; i <= 30; i += 5)
{
calories_burned = (i * CALORIES_BURNED_PER_MIN);
   printf("calories burned after %d minutes = %d\n",i,calories_burned);
}

return 0;
}
