Goto Statememt Print Text in C
This is a C program that prompts the user to enter an integer 'n' and then uses the goto statement to print the string "Hi" 'n' times.
- The #include<stdio.h> is a preprocessor directive that includes the contents of the standard input-output library in the program.
- The int main() function is the starting point of the program execution. Inside the main function, an integer n and a counter i is declared and initialized to 1.
- printf() is used to display the prompt for the user to enter the limit, and scanf() is used to get the input and store it in the variable 'n'.
- A label start is defined and a goto statement is used to jump to this label. The code between the label and the goto statement will execute repeatedly until the condition i<=n is false.
- The first time the code is executed, the string "Hi" is printed and the value of i is incremented by 1. Then the condition i<=n is checked, if it's true the control jumps back to the label 'start' and the same process is repeated until the condition is false.
- It is worth noting that the use of the goto statement is generally discouraged in modern programming because it can lead to unstructured and hard-to-maintain code.
- Alternative control structures such as for loops, while loops or do-while loops can be used for the same purpose and are considered more readable, maintainable and less prone to errors.
Finally, the return 0 statement is used to indicate the successful execution of the program. The return value of 0 is a convention used to indicate that the program has executed correctly.
