Take a close look about the pattern and identify some noticeable things about it. Here are some.
1.The pattern consists of N * 2 - 1 rows.
2.When you look to the center horizontal plus line i.e. +++++++++ this line. It also consists of N * 2 - 1 columns.
3.For every other row, single plus symbol is printed after N - 1 blank spaces.
Based on the above observation let us write a C program to print plus star pattern.
Program to print plus star pattern series
/** * C program to print the plus star pattern series */ #include <stdio.h< int main() { int i, j, N; printf("Enter N: "); scanf("%d", &N); // Run an outer loop from 1 to N*2-1 for(i=1; i<=(N * 2 - 1); i++) { // For the center horizontal plus if(i == N) { for(j=1; j<=(N * 2 - 1); j++) { printf("+"); } } else { // For spaces before single plus sign for(j=1; j<=N-1; j++) { printf(" "); } printf("+"); } printf("\n"); } return 0; }
Output
Enter N: 5
