After reading this C goto statement topic, you will understand its theory and examples also you will able to implement goto statement in C programming.
C goto statement is an unconditional jump statement and goto statement used to jump the program control to the specified C programming statement.
C goto statement syntax:
The syntax of goto statement is given below,
goto label;
where, the label is an identifier. When goto statement executes, the program control jumps to label which targets the specified C programming statement.
Example:
Program (1): To area of Square using goto statement.
#include<stdio.h>
#include<conio.h>
void main(void)
{
float side, area;
back:
printf("\n Enter the value of side of square: ");
scanf("%f", &side);
if(side < 0)
{
printf("Side of square should not be negative");
goto back;
}
area = side * side;
printf("%f", area);
getch();
}
Output (1)
Enter the value of side of square: -3 Side of square should not be negative Enter the value of side of square: 5 25.000000
