Could anyone help with writing this program in C? I am stuck and have no idea where to start.

A diagonally dominant matrix is a matrix A such that for each row, the absolute value of the diagonal element on that row is strictly larger than the sum of the absolute values of all other elements in the row. That is, for each row i-0,n-1, the following holds: j-0.ji Write a function is_diag_dom() that determines if an N-by-N matrix mat is diagonally dominant (it returns 1 if the matrix is diagonally dominant and 0 otherwise). The function prototype has to be int is_diag_dom( int mat[ I[N]) You may use the function fabs()with prototype double fabs(double x), from the C standard math library, which returns the absolute value of x. Write a program to test this function. Note that N represents a constant. To set a value to N use the define directive at the beginning of the file (E. g.: #define N 20 replaces N by 20 all over the file, except for occurrences of N inside a string or a variable name). Write a program to test the function
