A switch statement allows a variable to compare with case labels for equality if match that statement is going to be executed. Each case labels are compared with the switch statement or variable, if matched then that case-labels implemented otherwise default statement is going to be print.
Example of Switch Case:
#include<stdio.h>//header file for standard input and output
int main()//main function defined as integer
{//main func braces opened
int mn;//variable mn of integer type to store month number
printf("Enter the month number");//print message
scanf("%d".&mn);//user input for month number
switch(mn)//switch case to test cases for month name
{//switch case braces opened
case 1://start of test cases as 1,2,3…12 as there are 12 months
printf("January");//print message
break;//break statement, if this particular case satisfies then it comes out of the switch block
case 2:
printf("Feburary");
break;
case 3:
printf("March");
break;
case 4:
printf("April");
break;
case 5:
printf("May");
break;
case 6:
printf("June");
break;
case 7:
printf("July");
break;
case 8:
printf("August");
break;
case 9:
printf("September");
break;
case 10:
printf("October");
break;
case 11:
printf("November");
break;
case 12:
printf("December");
break;
default://it gets encountered where there is no match from the above test cases for instance in this program if the month number is greater than 12 this gets encountered as we do not have any month after 12
printf("Invalid Month number");
}//switch case braces closed
return 0;
}//main function braces closed
