In this tutorial, we are going to have a brief look on how to code 13 simple number patterns just by changing variables values using the SAME loop for all patterns in c language.
This tutorial is very easy and interesting. I assure that you will enjoy the whole tutorial on patterns.
To understand these patterns, you should have a good knowledge of C language Loops. So that you could easily grasp what is happening inside the Loops.
Point to Note:
Below patterns are obtained by just changing the variables in the Loops.
Small Note:
Loops play a key role in programming. If you try to understand patterns then you could easily master Loops. My suggestion to you is to practice and understand the patterns as many you can.
Coming to the concept, set the first one as your core pattern, and rest are derived from it.
Half-Pyramid Pattern: Type #1
Loop: #1 => 1. i = rows, 2. i >= 1, 3. i--
Loop: #2 => 4. j = 1, 5. j <= i, 6. j++, printint(j)
#include <stdio.h>
void main() {
int rows, i, j;
printf("Enter Number Of Rows You Want: ");
scanf( "%d", &rows );
for(i = rows; i >= 1; i--) {
for(j = 1; j <= i; j++) {
printf("%d ", j);
}
printf("\n");
}
}
Output:
Enter Number Of Rows You Want: 6
1 2 3 4 5 6
1 2 3 4 5
1 2 3 4
1 2 3
1 2
1
Half-Pyramid Pattern: Type #2
Same Loop as above, but printing (i)
#include <stdio.h>
void main() {
int rows, i, j;
printf("Enter Number Of Rows You Want: ");
scanf("%d", &rows);
for(i = rows; i >= 1; i--) {
for(j = 1; j <= i; j++) {
printf("%d ", i);
}
printf("\n");
}
}
Output:
Enter Number Of Rows You Want: 5
5 5 5 5 5
4 4 4 4
3 3 3
2 2
1
Half-Pyramid Pattern: Type #3
Loop: #1 => 1. i = rows, 2. i >= 1, 3. i--
Loop: #2 => 4. j = i, 5. j >= 1, 6. j--
then print (j)
#include <stdio.h>
void main(){
int rows, i, j;
printf("Enter Number Of Rows You Want: ");
scanf("%d", &rows);
for(i = rows; i>=1; i--){
for(j = i; j>=1; j--){
printf("%d ", j);
}
printf( "\n" );
}
}
Output:
Enter Number Of Rows You Want: 6

void main() {
int rows, i, j;
printf("Enter Number Of Rows You Want: ");
scanf("%d", &rows);
for(i = 1; i <= rows; i++) {
for(j = rows; j >= i; j--) {
printf("%d ", j);
}
