The goto statement is rarely used because it makes program confusing, less readable and complex. Also, when this is used, the control of the program won’t be easy to trace, hence it makes testing and debugging difficult.
C – goto statement
When a goto statement is encountered in a C program, the control jumps directly to the label mentioned in the goto stateemnt

The C goto statement is also known as jump statement. It is used to transfer control to the other part of the program. It unconditionally jumps to the specified label. The jump statements defined in C are break, continue, goto and return. In addition to these jump statements, a standard library function exit is used to jump out of an entire program. The break Statement: The break statement is extensively used in loops and switch statements. Pernyataan GOTO menggunakan keyword “goto” diikuti nama label berfungsi untuk memberi tahu CPU agar melompat ke baris yang miliki label dengan nama tersebut. Pernyataan LABEL di isi dengan nama label diakhiri dengan tanda titik dua, berfungsi untuk menandai suatu baris program, tempat dimana loncatan CPU karena GOTO mendarat.
Example of goto statement
Output:
Explanation: In this example, we have a label
addition and when the value of i (inside loop) is equal to 5 then we are jumping to this label using goto. This is reason the sum is displaying the sum of numbers till 5 even though the loop is set to run from 0 to 10.

The goto statement is a control flow statement that causes the CPU to jump to another spot in the code. This spot is identified through use of a statement label. The following is an example of a goto statement and statement label:
Use of auto-tune in dci shows. In this program, the user is asked to enter a non-negative number. However, if a negative number is entered, the program utilizes a goto statement to jump back to the tryAgain label. The user is then asked again to enter a new number. In this way, we can continually ask the user for input until he or she enters something valid.
In the section on variables, we covered three kinds of scope: local (block) scope, file scope, and global scope. Statement labels utilize a fourth kind of scope: function scope. The goto statement and its corresponding statement label must appear in the same function.
There are some restrictions on the use of goto statements. For example, you can’t jump forward over a variable that’s initialized in the same block as the goto:
In general, use of goto is shunned in C++ (and most other high level languages as well). Edsger W. Dijkstra, a noted computer scientist, laid out the case in a famous but difficult to read paper called Go To Statement Considered Harmful. The primary problem with goto is that it allows a programmer to cause the point of execution to jump around the code arbitrarily. This creates what is not-so-affectionately known as spaghetti code. Spaghetti code is code that has a path of execution that resembles a bowl of spaghetti (all tangled and twisted), making it extremely difficult to follow the logic of such code.
As Dijkstra says somewhat humorously, “the quality of programmers is a decreasing function of the density of go to statements in the programs they produce”.
Goto statements are common in some older languages, such as Basic or Fortran, and even used in C. However, in C++, goto statements are almost never used, as almost any code written using a goto statement can be more clearly written using other constructs in C++, such as loops, exception handlers, or destructors (all of which we’ll cover in future lessons).
