                              C Program to Print Pattern

To print the following pattern.
1*2*3*4
9*10*11*12
13*14*15*16
5*6*7*8

C Program:

#include <stdio.h>

int main()

{

int arr[100],n,i,j,count = 1, num=0;

scanf("%d",&n);

for(i=1;i<=n;i++)

{

if(i%2!=0){

for(j=1;j<=n;j++)

{

printf("%d",count);

if(j!=n)

printf("*");

count++;

}

printf("\n");

}

else{

for(j=1;j<=n;j++)

{

arr[num]=count;

count++;

num++;

}

}

}

for(i=1;i<=n/2;i++)

{

int num2=0;

num2=num-(i*n);

for(j=1;j<=n;j++)

{

printf("%d",arr[num2++]);

if(j!=n)

printf("*");

}

printf("\n");

}

return 0;

}
