just 2 minor edits.. 1. you forgot # preprossed ststements start with a # symbol in C 2. you didn't considered non square matrix . here's the modified code . https://code.sololearn.com/creX6I3JkQUe/?ref=app and one more thing . please post your code on code playground (may be keep it private if you want to) and provide us with a link . that saves our time a little.

include<stdio.h> int main() { int i, j, rows, columns, a[10][10], Sum = 0; printf("\n Please Enter Number of rows and columns : "); scanf("%d %d", &i, &j); printf("\n Please Enter the Matrix Elements \n"); for(rows = 0; rows < i; rows++) { for(columns = 0;columns < j;columns++) { scanf("%d", &a[rows][columns]); } } for(rows = 0; rows < i; rows++) { Sum = Sum + a[rows][rows]; } printf("\n The Sum of Diagonal Elements of a Matrix = %d", Sum ); return 0; }

HASHEM AL_NASRE your question description state about a square 5x5 a(rray) but in your code you declare a 10x10 array and ask user for two dimensions (wich could be everything: not equals -- not square -- as well as greater than 10)... anyway, Prashanth Kumar [back again] is right for its first point: 'include' preprocessor statement should start with '#' (maybe you have it in your original code and you doesn't select it when copy-pasting: that's one reason why it is better to share a link to your code rather than copy pasting it ^^)
