For Loop Pattern Programs in C Programming

---

For Loop Pattern Programs in C Programming refers to a specific type of program that uses for loops to generate a specific pattern or shape. These programs use nested for loops and conditional statements to print characters such as stars, numbers, letters, etc. in a specific pattern. This type of program is commonly used to practice and improve understanding of loops and conditional statements in C programming. Examples of patterns that can be created with for loop include pyramid, diamond, triangle, and many more

Source Code Example : 1

#include<stdio.h>
int main()
{
  int i,j,a;
  printf("\nEnter the value:");
  scanf("%d",&a);
  for(i=1;i<=a;i++)
  {
    printf("\n");
    for(j=1;j<=i;j++)
    {
      printf("%d",i);
    }
  }
  return 0;
}
