How to print given star pattern.

-

What we be the general solution of given star pattern in C programming language.                                                                     







This programming is executed on Dev C++ editor. You may run this programming program on any C or C++ editor.

1st way for Star pattern programming.

#include<stdio.h>         
#include<conio.h>
int main()
{
int row, col, n;                                         // data type deceleration.        
printf("Enter The number of row");
scanf("%d",&n);                                   //   taking input for the number of rows.                
for(row=1;row<=n;row++)                  //for rows.
{
for(col=1;col<=row;col++)        // for columns.
{                                               
printf("*");                         //printing the star in for given pattern.
}
printf("\n");                               // for new line.       
}
return 0;
}

Output:-

Enter The number of row 5

This is general solution of given pattern. In this I have entered 5 for number of rows. It's your choice how much you enter the number of rows the pattern will be same with your number of rows.

There is also another solution for this question but it is not the best way because it is not more effective like 1st one. The best programming is the one which consume less memory and less time for execution. So the next programming for only knowledge purpose because it consume more time to execute. 

2nd way for  Star pattern programming.

#include<stdio.h>
#include<conio.h>
int main()
{
int row, col, n;                                       // data type deceleration.        
printf("Enter The number of row");
scanf("%d",&n);                                   //   taking input for the number of rows.
for(row=1;row<=n;row++)                  //for rows.
{
for(col=1;col<=n;col++)              // for columns
{
if(col<=row)                       //condition for printing start.
{
printf("*");
}
else                                  // for free space.
{
printf(" ");
}
}
printf("\n");                          //new line.
}
getch();
return 0;
}

Output:-

Enter The number of row 5
*
**
***
****
*****

This programming is not the best solution for this start pattern because this consume more time and more space. So I will always prefer the 1st solution for this star pattern.

What will be the programming for Abundant Number?  Today topic is  Abundant Number. we will discuss about, what is  Abundant Number, what are the examples of  Abundant Number, and its programming stuff with program, logic, some output either number is  Abundant Number or not. What is Abundant Number? Abundant Number are same as  Perfect Number  but there is  slit difference, that a number is  Abundant Number when it factor sum or divisor sum is greater then the number, means when we find factor or divisor then the sum of all divisor or factor except that number is greater then that number it is called  Abundant Number. Example:- Let us take a number 30 when we find its divisor we will get 1, 2, 3, 5, 6, 10, 15, 30. But we will not include 30, so sum is :- 1 + 2 + 3 + 5 + 6 + 10 + 15 = 42 which is greater then the original number, so 30 is  Abundant Number.   Let take another number 29 when we will find its divisor  we...

What will be the programming of Automorphic Number? Today we are going to learn about the  Automorphic Number .  We will learn definition , some example, programming and logic behind the  Automorphic Number   and also look at the output either input number is  Automorphic Number   or not. What is Automorphic Number? Automorphic Number is a such type of mathematical number whose square end is equal to the original number. Means if you square the number then the end of that number is equal to original number. Example:- Lets take 5. Then square of it is 25 and this numbers ends with 5 , and last number is equal to original number. Another example 7. Then the square of this number is 49 and end number is 9, which is not equal to the original number. Programming :- #include<stdio.h> #include<conio.h> #include<math.h> int main() { int num, temp,sqrNum, count,last,temp1;    //Data type decelaration printf( "Enter the numb...
