This sounds very much like a homework problem. If you work on it and get started, you found a great place to ask a specific question. However, this is not a place to have your homework done for you.

I've written the function for a 3x3 matrix. In 3x3 upper triangular matrix, there are 3 elements whose value is 0 (i < j).. So, when count is 3, program will display that matrix is upper triangular. You can modify the function as per your matrix size.

void upper() // Function for finding Upper Triangular Matrix
{
int count = 0;
printf("\nEnter a matrix ");
for(i = 0; i <= 2; i++)
for(j = 0; j <= 2; j++)
scanf("%d", &a[i][j]);

for(i = 0; i <= 2; i++)
{
for(j = 0; j <= 2; j++)
{
if(i <= j)
{
if(a[i][j] == 0)
count++;
}
}
}
if(count == 3)
printf("\nThe Matrix is upper triangular\n");
else
printf("\nThe Matrix is not upper triangular\n");
}

int main() // Main Function
{
upper();
)

Is uppercase used in a C program?

By convention, all upper-case is used to identify macros and single capitals to identify template parameters. However, programmers are free to use upper-case as they see fit.

What is strictly lower triangular matrix?

A strictly lower triangular matrix is a kind of (lower) triangular matrix. Term "lower" implies matrix has elements only in the lower half. The condition "strictly" implies that even the "diagonal" of such lower triangular matrix is populated with '0's. The strictly lower triangular matrix thus has '0's in its diagonal as well as the upper triangle part. In other words, a strictly lower triangular matrix is a lower triangular matrix minus its diagonal.
