C program to read and print a scalar matrix?

Answer 1

Here is the C program to check whether the inputted matrix is scalar matrix or not. ( its not my creation, its get from other website,am not check)

#include<stdio.h>

#include<conio.h>

int main()

{

int a[10][10],i,j,m,n,f=0;

printf("Enter the order of the matrix\n");

scanf("%d%d",&m,&n);

printf("Enter the matrix\n");

for(i=0;i<m;i++)

{

for(j=0;j<n;j++)

{

scanf("%d",&a[i][j]);

}

}

if(m!=n)

{

printf("The matrix is not identity");

}

else

{

for(i=0;i<m;i++)

{

for(j=0;j<n;j++)

{

if((i==j&&a[i][j]!=a[0][0])(i!=j&&a[i][j]!=0))

{

printf("The matrix is not scalar\n");

f=1;

break;

}

}

if(f==1)

{

break;

}

}

if(f==0)

{

printf("The matrix is scalar\n");

}

}

getch();

return 0;

}
