C programming tutorials for Beginners – C goto Statement

(C Programming Tutorials)

C goto Statement

In this tutorial, you will learn to create the goto statement in C programming. Also, you will learn when to use a goto statement and when not to use it.

Syntax of goto Statement

goto label;
... .. ...
... .. ...

The label is an identifier. When the goto statement is encountered, the control of the program jumps to label: and starts executing the code.

How goto statement works?

Example: goto Statement

// Program to calculate the sum and average of positive numbers
// If the user enters a negative number, the sum and average are displayed.

#include <stdio.h>

int main(){

   const int maxInput = 100;
   int i;
   double number, average, sum = 0.0;

   for (i = 1; i <= maxInput; ++i) {
      printf("%d. Enter a number: ", i);
      scanf("%lf", &number);
      // go to jump if the user enters a negative number
      if (number < 0.0) {
         goto jump;
      sum += number;

   average = sum / (i - 1);
   printf("Sum = %.2fn", sum);
   printf("Average = %.2f", average);

   return 0;


1. Enter a number: 3
2. Enter a number: 4.3
3. Enter a number: 9.3
4. Enter a number: -2.9
Sum = 16.60
Average = 5.53

Reasons to avoid goto

The use of goto statement may lead to code that is buggy and hard to follow. For example,

for (i = 0; i < number; ++i)
    test += i;
    goto two;
if (test > 5) {
  goto three;
... .. ...

Also, the goto statement allows you to do bad stuff such as jump out of the scope.

That being said, goto can be useful sometimes. For example: to break from nested loops.

Should you use goto?

If you think the use of goto statement simplifies your program, you can use it. That being said, goto is rarely useful and you can create any C program without using goto altogether.

Here’s a quote from Bjarne Stroustrup, creator of C++, “The fact that ‘goto’ can do anything is exactly why we don’t use it.”
