Switch Statement in C Language – BCA Notes

The switch statement in C is another type of decision-making statement. It allows the program to choose from multiple options based on the value of a variable. In this post by BCA School, you’ll learn the syntax, working, and examples of the switch statement in C.

🔹 What is a Switch Statement?

A switch statement tests a variable against multiple values. When a match is found, the corresponding block of code is executed. It is more efficient than multiple if-else statements for handling multiple conditions.

🔹 Syntax of Switch Statement

switch(expression) {
    case value1:
        // statements
        break;
    case value2:
        // statements
        break;
    ...
    default:
        // statements
}

🔹 Example of Switch Statement

#include <stdio.h>
int main() {
    int day = 3;
    switch(day) {
        case 1:
            printf("Monday");
            break;
        case 2:
            printf("Tuesday");
            break;
        case 3:
            printf("Wednesday");
            break;
        default:
            printf("Invalid day");
    }
    return 0;
}

🔹 Key Points About Switch Statement

• Used to replace multiple if-else statements when testing a single variable.
• Each case must end with a break to prevent “fall-through”.
• default block executes when none of the cases match.
• Switch works only with integer, character, or enumerated values.

🎯 Conclusion

The switch statement simplifies decision-making for multiple conditions and makes code cleaner and more readable. BCA students should practice switch statements along with if-else to handle different scenarios efficiently.
