C program to represent the numbers in spiral pattern
The spiral pattern to represent the numbers is shown below −
The logic applied to print the numbers in spiral pattern is as follows −
for(i=1;i<=rows*2;i+=2){
if(k%2==1){
printf("%3d %3d",i,i+1);
k++;
}else{
printf("%3d %3d",i+1,i);
k++;
}
printf("
");
}Program
Following is the C program for representing the numbers in spiral pattern −
#include<stdio.h>
main(){
int i,rows,k=1;
printf("Enter number of Rows for Spiral Pattern
");
scanf("%d",&rows);
for(i=1;i<=rows*2;i+=2){
if(k%2==1){
printf("%3d %3d",i,i+1);
k++;
}else{
printf("%3d %3d",i+1,i);
k++;
}
printf("
");
}
}Output
When the above program is executed, it produces the following result −
Enter number of Rows for Spiral Pattern 10 1 2 4 3 5 6 8 7 9 10 12 11 13 14 16 15 17 18 20 19
