C: Handling menu commands with switch statements

Use the switch statement to process the menu command. In many applications, the process is controlled by a menu, such as entering a'a'or 'a' character from the keyboard, a operation is performed , and a ' b' or 'b' character, the b operation will be performed .

Solution: Program:

#include <stdio.h>

void Add (int x, int y)

{

printf ("x+y=%d\n", x + y);

}

void Mul (int x, int y)

{

printf ("x*y=%d\n", x * y);

}

int main ()

{

void Add (Int,int), Mul (Int,int);

Char ch;

int a = n, b = 23;

ch = getchar ();

Switch (CH)

{

Case ' a ':

Case ' A ': Add (A, b);

Break

Case ' B ':

Case ' B ': Mul (A, b);

Break

Default:putchar (' \a ');

Break

}

return 0;

}

Results:

A

x+y=38
