TEST 1-MONDAY

Write a program to calculate mass of the liquid in a tank. Allow the user to input the
volume either in cm or meter, and prompt the user to recalculate if desire.

Note that:

Oil density (ρ)= 850 kg/m3

Mass=ρV

The output should be similar to:


#include<stdio.h>

#include<conio.h>

#include<math.h>

main(){

float oildensity, tankvolume,mass=0;

char oilunit,again;

printf("This program calculate the mass of oil in a tank");

start:

printf("nnEnter oil density: ");scanf("%f",&oildensity);

printf("Enter tank volume: ");scanf("%f",&tankvolume);

printf("nEnter volume unit(m=meter, c=centimeter): ");scanf("%s",&oilunit);

recalculate:

switch (oilunit){

mass= oildensity*((pow(tankvolume,3))/pow(100,3)); break;

case 'm':

mass= oildensity*(pow(tankvolume,3)); break;

printf("You have entered a wrong type of unit");

printf("nnEnter oil density unit(g for gram/k for kg): ");scanf("%s",&oilunit);

goto recalculate; }

printf("nntThe Mass of oil is %.4fkg",mass);

printf("nnDo you want to re-calculate: ");scanf("%s",&again);
