goto statement Flowchart
The following flowchart will clearly demonstrate, how goto statement works
goto statement Program
Let's take a look at the goto statement in action. In the following program we will print whether the number is positive or negative using goto statement
#include <stdio.h>
int main()
{
int num;
printf("Enter a positive or negative integer number:\n ");
scanf("%d",&num);
if(num >= 0)
goto pos;
else
goto neg;
pos:
{
printf("%d is a positive number",num);
return 0;
}
neg:
{
printf("%d is a negative number",num);
return 0;
}
}
- Enter a positive or negative integer number:
- 2
- 2 is a positive number
Note:
In this program, the user entered number is checked for positive or negative number. If the user entered number is positive, the control is passes to pos : by goto statement. If the user entered number is negative, the control is passes to neg : by goto statement.
