Pyramid, Star Series and Patterns Programs in C language | C programming

Hi, I'm Golam Rabbani. Today I will discuss
about Pyramid, Star Series and Patterns Programs.

Greetings! How are you all? Hope everyone is well.

At first we have to know that what is Pyramid,
Star Series and Patterns Programs?

Just it grow your skill for handling loop.
How to control your loop, that’s it.

Let’s go……

@Program 1:

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

/*
Output:
   1
   11
   111
   1111
   11111
*/

Output:

@Program 2:

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

/*
Output:
     111111
     11111
     1111
     111
     11
     1
*/

Output:

@Program 3:

#include<stdio.h>
int main(){
    int i,j,k,n;
    printf("Enter number: ");
    scanf("%d", &n);
    for(i=0; i<=n; i=i+1){
        for(j=0; j<=i; j=j+1){
            printf(" ");
        }
        for(k=0; k<=n-i; k=k+1){
            printf("1");
        }
        printf("\n");
    }
