Goto statement overview in C - Mini Project: Build & Apply

Goto statement overview

📖 Scenario: Imagine you are writing a simple program that checks numbers and jumps to a special message when a certain number is found.

🎯 Goal: You will create a program that uses the goto statement to jump to a label when a number matches a condition.

📋 What You'll Learn

Create an integer variable called number with the value 5

Create an integer variable called target with the value 5

Use an if statement to check if number equals target

Use goto to jump to a label called found if the condition is true

Print a message before and after the goto statement

Create a label called found that prints a special message

💡 Why This Matters

🌍 Real World

Sometimes, <code>goto</code> is used in low-level programming or error handling to jump to cleanup code quickly.

💼 Career

Understanding <code>goto</code> helps you read and maintain legacy C code and understand program flow control.

1

Create the initial variables

Create an integer variable called number and set it to 5.

C

// Your code here

Need a hint?

Use int number = 5; to create the variable.

2

Add the target variable

Create an integer variable called target and set it to 5.

C

int number = 5;
// Your code here

Need a hint?

Use int target = 5; to create the variable.

3

Use goto to jump when numbers match

Write an if statement that checks if number equals target. Inside the if, use goto found;. Before the if, print "Checking numbers...". After the if, print "This will be skipped if numbers match.". Create a label called found that prints "Number matched! Jumped to label.".

C

int number = 5;
int target = 5;
// Your code here

Need a hint?

Use if (number == target) { goto found; } and place the prints as instructed.

4

Print the final output

Run the program and print the output to show the goto statement worked.

C

int number = 5;
int target = 5;

#include 

int main() {
    printf("Checking numbers...\n");
    if (number == target) {
        goto found;
    }
    printf("This will be skipped if numbers match.\n");

found:
    printf("Number matched! Jumped to label.\n");
    return 0;
}

// Run the program to see the output

Need a hint?

When you run the program, it should print the first and last messages only.
