-Here we try to compare two matrix that they are equal or not.
program-
#include< stdio.h>
int main()
{
int a[10][10],b[10][10],r1,c1,r2,c2,i,j;
printf("Enter rows and columns in matrix_1\n");
scanf("%d%d",&r1,&c1);
printf("Enter %d numbers in matrix\n",r1*c1);
for(i=0;i< r1;i++)
{
for(j=0;j< c1;j++)
scanf("%d",&a[i][j]);
}
printf("Enter rows and columns in matrix_2\n");
scanf("%d%d",&r2,&c2);
printf("Enter %d numbers in matrix\n",r2*c2);
for(i=0;i< r2;i++)
{
for(j=0;j< c2;j++)
scanf("%d",&b[i][j]);
}
//Now compare both matrix
if(r1==r2 && c1==c2)
{
for(i=0;i< r1;i++)
{
for(j=0;j< c1;j++)
{
if(a[i]!=b[i])
{
printf("Both are different");
exit(0);
}
}
}
printf("Both are same");
}
else
{
printf("Both are different");
}
}
Enter rows and columns in matrix_1
2 2
Enter 4 number in matrix
1 2 3 4
Enter rows and columns in matrix_2
2 2
Enter 4 number in matrix_2
1 2 3 4
Both are same
Enter rows and columns in matrix_1
2 2
Enter 4 number in matrix
1 2 3 4
Enter rows and columns in matrix_2
3 3
Enter 9 number in matrix
1 2 3 4 5 6 7 8 9
Both are Different
