C Case Statement

C case statement

Created By: chatGPT

In C programming, a case statement is part of the switch statement, which allows you to execute different parts of code based on the value of a variable. It provides a convenient way to handle multiple conditions compared to using multiple if-else statements. Below is a simple example demonstrating how to use a switch-case structure.

#include <stdio.h>

int main() {
    int day;
    printf("Enter a number (1-7) for the day of the week: ");
    scanf("%d", &day);

    switch (day) {
        case 1:
            printf("Monday\n");
            break;
        case 2:
            printf("Tuesday\n");
            break;
        case 3:
            printf("Wednesday\n");
            break;
        case 4:
            printf("Thursday\n");
            break;
        case 5:
            printf("Friday\n");
            break;
        case 6:
            printf("Saturday\n");
            break;
        case 7:
            printf("Sunday\n");
            break;
        default:
            printf("Invalid input! Please enter a number between 1 and 7.\n");
            break;
    }
    return 0;
}

In this code: The user is prompted to enter a number corresponding to a day of the week. The switch statement then checks the value of the day variable. Each case corresponds to a specific day, and when a matching case is found, the code associated with that case executes. The break statement ensures that the program exits the switch once a case is processed, preventing fall-through to the subsequent cases. If the input does not match any case, the default case provides a message indicating invalid input.

// Input: 3
// Output: Wednesday
