Program 168:To Interchange of Diagonals in Matrix

Program 168:

#include<stdio.h>
main()
{ 
 int i,j,rows,col,temp;
 printf("Enter number of rows\n");
 scanf("%d %d",&rows,&col);

 
 int a[rows][col];
 if(col==rows)
 {
   //Taking input for matrix
 printf("Enter Matrix 1\n");
  for(i=0;i<rows;i++)
  {
  for(j=0;j<col;j++)
  {
   scanf("%d",&a[i][j]);
  }
  }
  printf("The given Matrix is\n");
  for(i=0;i<rows;i++)
  {
  for(j=0;j<col;j++)
  {
   printf("%d\t",a[i][j]);
  }
  printf("\n");
  }
  
  for(i=0;i<rows;i++)
  {
   temp=a[i][i];
   a[i][i]=a[i][rows-i-1];
   a[i][rows-i-1]=temp;
   
  }
  
   printf("The Matrix After Interchanging Diagonals is\n");
  for(i=0;i<rows;i++)
  {
  for(j=0;j<col;j++)
  {
   printf("%d\t",a[i][j]);
  }
  printf("\n");
  }
}
 else
 {
  printf("Not Possible\n");
 }
 
  
}
