compiler is used to translate the high-level language program into machine code at a time. It doesn't require special instruction to store in a memory, it stores automatically. the execution time is less compared interpreter.

A compiler is a program that translates a source program written in some high-level programming langualge (such as Java) into machine code for some computer architecture (such as the Inter Pentium archiecture).

It is also called as post tested loop. It is used when it is necessary to execute the loop at least one time. Syntax:

do {
Loop body
} while (Expression);

Example:

int main(){

         printf("To exit press  2");
         scanf("%d",&num);
         ++i;
         switch(num){
             case 1:printf("You are welcome\n");break;
             default : exit(0);
         }
    }
    while(i<=10);
    return 0;
}

Output: 3 3 4 4
