switch statement - Basic C Program

C Program to use the computer as calculator. The user input a code +,‒,,/ and values that are to be computed.

/* Program to use the computer as calculator */

#include <stdio.h>

main()

{

int a,b,c=0;

char op;

printf("CALCULATION CODE");

printf("\n+ADD\n‒SUB\n*MUL\n/DIV\n");

printf("Enter Code.....");

scanf("%c",&op);

printf("Enter values.....");

scanf("%d %d",&a, &b);

switch(op)

{ /* switch open */

case '+':c=a+b;

break;

case '‒': c=a‒b;

break;

case '*': c=a*b;

break;

case '/': c=a/b;

break;

} /* switch */

printf("\nResult is.....%d", c);

getch();

} /* main */

OUTPUT

CALCULATION CODE

+ADD

‒SUB

*MUL

/DIV

Enter Code.....+

Enter values.....20 10

Result is.....30

EXPLANATION: In the program the switch statement consists of four options. The option is entered according to user's choice. The four options are addition, subtraction, multiplication and division. Each option contains several operations. Thus statement is executed according to selected choice. In the program the character variable op reads the character entered by the users. According to the entered character, the switch statement is executed and prints the output.
