Explain Program

Step :1

#include<stdio.h>

• standard input-output header file use printf() and scanf().

Step :2

void main()

• main function  execution starts.

Step :3

 Variable Declarations

int i, j, r;

• r: Number of rows for the pattern (user input).

• i: Controls the outer loop (rows).
• j: Controls the inner loop (columns/numbers in each row).

Step :4

printf("enter the number");

scanf("%d", &r);

•  user to enter the number of rows.

Step :5

Outer Loop – Controls the Rows

for(i = 1; i <= r; i++)

• Starts 1 and goes up to r.

• Each iteration print one row of the triangle.

Step :6

for(j = 1; j <= i; j++)

{

    printf("%d", j);

}

•  each row i, it prints numbers from 1 to i.

Step :7

printf("\n");

cursor to the next line

Step :8

return 0;
