The Goto statement in C Programming is used to alter the flow of a program. When the compiler reaches the goto statement then it will jump unconditionally ( both forward and backward ) to the location specified in the goto statement (we called it as label).
Unlike, the Break Statement and Continue Statement goto statement doesn’t require any If Statements to perform.
Goto Statement Syntax
The label specified after the goto statement is the location where we place the statements to execute.
From the above syntax you can understand that, We can place the label anywhere in the program. It doesn’t matter if you put before the goto statement or after.
Goto Statement in C Example
This program allows the user to enter his/her individual subject marks then it will check whether the person is pass or fail using Goto Statement in C programming.
CODE

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 |
/* Goto Statement in C Programming example */ #include <stdio.h> int main() { int Totalmarks; printf(" \n Please Enter your Subject Marks \n "); scanf("%d", & Totalmarks); if(Totalmarks >= 50) { goto Pass; } else goto Fail; Pass: printf(" \n Congratulation! You made it \n"); Fail: printf(" \n Better Luck Next Time \n"); return 0; } |
OUTPUT
ANALYSIS
In the above code, Pass and Fail are the labels we used.
First we declared integer variable Totalmarks
|
1 |
int Totalmarks; |
In the next line, Printf statement will ask the user to enter his / her total marks and scanf statement will store the user specified value in Totalmarks variable
|
1 2 |
printf(" \n Please Enter your Subject Marks \n "); scanf("%d", & Totalmarks); |
In the next line we used If Else Statement in C to check whether user entered value is greater than or equal to 50.
|
1 2 3 4 5 6 |
if(Totalmarks >= 50) { goto Pass; } else goto Fail; |
If the condition is TRUE then Goto statement inside the If block will take the compiler to the Pass label and executed the statements in side the Pass label
|
1 |
printf(" \n Congratulation! You made it \n"); |
Else (If the condition is FLASE then) Goto statement inside the Else block will take the compiler to the Fail label and executed the statements in side the Fail label
|
1 |
printf(" \n Better Luck Next Time \n"); |
NOTE: Although all the programming languages supports goto statement but it is always good practice to avoid using it or at least minimise the usage. Instead of using goto statement in C, we can use the alternatives such as Break Statement in C, Continue Statement in C statements.
