### 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");
}

}```
