Switch Case In C

Phone Code Check Using C

A switch statement tests the value of a variable and compares it with multiple cases. Once the case match is found, a block of statements associated with that particular case is executed. Each case in a block of a switch has a different name/number which is referred to as an identifier.

Code of this program :

#include <stdio.h>
int main()
{
    int phone_code;
    printf("\n Enter phone code :");
    scanf ("%d", &phone_code);

    switch ( phone_code )
    {
    case 61 :
        printf("\n This phone_code area is Brasilia");
        break;
    case 71 :
        printf("\n This phone_code area is Salvador");
        break;
    case 11 :
        printf("\n This phone_code area is Sao palo");
        break;
    case 21 :
        printf("\n This phone_code area is Rio de janeiro");
        break;
    case 32 :
        printf("\n This phone_code area is Juiz de fora");
        break;
    case 19 :
        printf("\n This phone_code area is Campinas");
        break;
    case 27 :
        printf("\n This phone_code area is Vitoria");
        break;
    case 31 :
        printf("\n This phone_code area is Belo Horizonte");
        break;
    default :
        printf("\n It is not any phn_code area");
        break;
    }
    return 0;
}

After run the code result looks like :
