How to find Grade equivalent using C Language

This program was the first requested tutorial on C programming Language using the Turbo C++ IDE.

This source code will determine the corresponding equivalent of your grade using the conditional structure if & else and selective structure switch.

#include<stdio.h>

#include<conio.h>

float eq; // global variable

void main() // main function

{

clrscr();

int grade; // contains the value input

printf("enter your grade: ");

scanf("%d",&grade);

//conditions

if(grade <= 74 ) {

printf("FAILED");

eq = 5.00;

}

else if (grade >= 75 && grade <=100) {

printf("PASSED\n");

switch (grade){

case 75: case 76: case 77:

eq = 3.00; break;

case 78: case 79: case 80: case 81:

eq = 2.75; break;

case 82: case 83:

eq = 2.50; break;

case 84: case 85: case 86:

eq = 2.25; break;

case 87: case 88: case 89:

eq = 2.00; break;

case 90: case 91: case 92:

eq = 1.75; break;

case 93: case 94: case 95:

eq = 1.50; break;

case 96: case 97: case 98:

eq = 1.25; break;

case 99: case 100:

eq = 1.00; break;

default:

break;

}

}

else {

printf("invalid\n");

}

printf("your equivalent grade is: %.2f",eq);

getch();
