(probably a dumb question, but meh) e.g. if (number == 1) int identifier = "value1"; else if (number == 2) int identifier = "value2"; when using if or else if, can i initialize something instead of printing? (probably a dumb question, but meh)

e.g.
if (number == 1)
int identifier = “value1″;
else if (number == 2)
int identifier = “value2″;

Using curly braces in a case statement is a matter of coding style, because most compilers allow different variations. In this case the <strong>b</strong> statement has multiple printf statements and <strong>a </strong> has not. Therefore<strong> b</strong> has curly braces and <strong>a</strong> has not. Just as you can do with the if statement, where you use curly braces if there is more than one statement that needs to be run if the if statement is valid. You can try it yourself, make little programs and see what is allowed by the compiler. But whatever style you choose (no curly braces, only with multiple statements you use curly braces or always curly braces) try to be consistent, especially if you work with different people on the same code! @reshma: you are right.

#include<stdio.h>

int main()
{
char myinput;
int i=5;
printf("Which option will you choose:\n");
printf("a) Program 1 \n");
printf("b) Program 2 \n");
scanf("%c", &myinput);

switch (myinput)
{
case 'a':
printf("Run program 1\n");
if( i == 5) {
printf("OK\n");
}
break;
case 'b':
{
printf("Run program 2\n");
printf("Please Wait\n");
break;
}
default:
printf("Invalid choice\n");
break;
}
return 0;
}
