C Program
C program to Print Alphabet G star pattern
Example :-
#include <stdio.h>
int main() {
int a, b;
int n = 7;
for (a = 0; a < n; a++) {
for (b = 0; b < n; b++) {
if ((a == 0 ||a == n - 1) && b > 0 && b < n - 1)
printf("*");
else if ((b == 0 && a > 0 && a < n - 1))
printf("*");
else if ((a == n / 2 && b >= n / 2) || (a >= n / 2 && b == n - 1))
printf("*");
else
printf(" ");
}
printf("\n");
}
return 0;
}
This C Program Print a pattern in the shape of the capital letter G using asterisks "*"
Explain Program
Step :1
#include
<stdio.h>
Includes the
standard input-output library to use functions like printf().
Step :2
int
main() { ... }
The entry
point of the program.
Step :3
int a, b;
Variables a
and b are loop counters:
- a controls rows
- b controls columns
Step :4
int n =
7;
dimension of the pattern is 7 × 7.
Step :5
Outer Loops
for (a = 0; a < n; a++)
loop
goes from row 0 to 6 (7 rows in total).
Step :6
Inner Loop:
for (b = 0; b < n; b++)
inner loop loop goes from column 0 to 6
Step :7
First
Condition
if ((a == 0 || a == n - 1) && b > 0 && b < n - 1)
- When the current row is the first
(0) or last (6) AND
- column is not the first or last
Step :8
Second Condition
else if ((b == 0 && a > 0 && a < n - 1))
- Column is the first (0) AND
- Row is between top and bottom (i.e., not row 0 or 6)
Step :9
🔹 Third Condition
else if ((a == n / 2 && b >= n / 2) || (a >= n / 2 && b == n - 1))
(a == n / 2 && b >= n / 2)
- Row is the middle row
- Column is middle or to the right
Step :10
(a >= n / 2 && b == n - 1)
- From the middle row down
- At the last column
Step :11
Else Condition
else
printf(" ");
- above conditions match, just print a space.
Final
Line
printf("\n");
returen 0;
