Print 1-10 numbers without using Conditional Loop i.e without using
- for Loop
- while Loop
- do-while Loop
This can be achieved in 3 ways :
- Using Printf Statement 10 Times.
- Using Recursive Function
- Using goto Statement.
- Recursive Main Function
Way 1 : Printf Statement 10 times
#include<stdio.h>
void main()
{
printf("1");
printf("2");
printf("3");
printf("4");
printf("5");
printf("6");
printf("7");
printf("8");
printf("9");
printf("10");
}- Use 10 Times Printf Statement .
Way 2 : Recursive Function
#include<stdio.h>
void printNumber(int value)
{
int i;
printf("%d\n",value);
i = value + 1;
if(i>10)
return;
printNumber(i);
}
void main()
{
printNumber(1);
}- Recursive function : Calling Itself .
- printNumber function calls itself so it is called Recursive function .
Way 3 : Using Goto Statement
#include<stdio.h>
void main()
{
int i=0;
Start :
i = i + 1;
printf("%d\n",i);
if(i< =10)
goto Start;
}Way 4 : Using Recursive Main
#include<stdio.h>
main()
{
static int i=1;
if(i<=10)
{
printf("%d\n",i++);
main();
}
}- Static variable inside a function means “once the variable has been initialized, it remains in memory until the end of the program”
