Write a C program to print the following star program. Also write down the algorithm

#include<stdio.h>

#include<conio.h>

int main()

{

 int num,r,c;

 printf("Enter loop repeat number(rows): ");

 scanf("%d",&num);
 for(r=1; r<=num; r++)

 {

  for(c=1; c<=r; c++)

     printf("*");

  printf("\n");
 }
 getch();

 return 0;

} 

Output

*
**
***
****
*****

step1: num<--0, r<--0, c<--0
step2: Read number num
step3: Repeat step 4 for r=1,2,3....num
step4: Repeat step 5 for c=1,2....r
                    Begin

        print "*"
                    End
step8: 
step9: go to next line
step10: r=r+1
        [end of loop step4]
step11: stop
