Program to print Interesting pattern in C++
In this tutorial, we will be discussing a program to print a given interesting pattern.
For this, we will be provided with the half-width of the pattern. Our task is to print a similar pattern according to the given width with its left and right portions being mirror images of one another.
Example
#include<stdio.h>
//printing the given pattern
void print_pattern(int n){
int i,j;
//printing the upper half
for (i=1; i<=n; i++){
for (j=1; j<=(2*n); j++){
// Left portion
if (i<j)
printf(" ");
else
printf("*");
// Right portion
if (i<=((2*n)-j))
printf(" ");
else
printf("*");
}
printf("\n");
}
//printing the lower half
for (i=1; i<=n; i++){
for (j=1;j<=(2*n);j++){
// Left portion
if (i>(n-j+1))
printf(" ");
else
printf("*");
// Right portion
if ((i+n)>j)
printf(" ");
else
printf("*");
}
printf("\n");
}
}
int main(){
print_pattern(6);
return 0;
}Output
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
