This article shows the list of available Star Pattern Programs in C programming language with an example of each using the for loop, while loop, functions, and do while loop.
Apart from the Star Pattern Programs, you can print Alphabet and Number patterns using the C programming language. Before you start reading this, I suggest you refer to the C tutorial and C Examples articles to understand the language and the remaining programs.
Star Pattern Programs in C
The following is the list of C programs to Print star patterns and shapes.
C Program to Print Diamond Star Pattern
The below example uses a nested for loop to iterate rows and print the diamond star pattern. Within this section, we show you different kinds of diamond patterns. For more examples >> Click Here.
#include<stdio.h>
void loopLogic(int rows, int i){
for(int j = 1; j <= rows - i; j++)
{
printf(" ");
}
for(int k = 1; k <= i * 2 - 1; k++)
{
printf("*");
}
printf("\n");
}
int main(void)
{
int i, rows;
printf("Enter Diamond Rows = ");
scanf("%d", &rows);
for(i = 1; i <= rows; i++)
{
loopLogic(rows, i);
}
for(i = rows - 1; i > 0; i--)
{
loopLogic(rows, i);
}
}
Output.
Enter Diamond Rows = 8
