Example: Bank Cash Withdrawal in C

// Bank Cash Withdrawal
#include <stdio.h>

int main() {
    float balance;      // Variable to store the current account balance
    float withdrawalAmount; // Variable to store the amount to be withdrawn

    // Step 1: Prompt user for initial account balance
    printf("Enter current account balance: ");
    scanf("%f", &balance);

    // Step 2: Prompt user for the amount to withdraw
    printf("Enter amount to withdraw: ");
    scanf("%f", &withdrawalAmount);

    // Step 3: Check if the withdrawal amount is valid (positive)
    if (withdrawalAmount <= 0) {
        printf("Invalid withdrawal amount. Please enter a positive value.\n");
    }
    // Step 4: Check if there are sufficient funds
    else if (withdrawalAmount <= balance) {
        // Perform the withdrawal
        balance -= withdrawalAmount;
        printf("Withdrawal successful!\n");
        printf("Remaining balance: $%.2f\n", balance);
    }
    // Step 5: Handle insufficient funds
    else {
        printf("Insufficient funds.\n");
        printf("Current balance: $%.2f\n", balance);
    }

    return 0;
