    Smile scan recusivly in to 2D array

    hello!
    i'm trying to write a code which get variable as int and put them at 2D array...
    this a code which i wrote, it is the first time i'm trying to do thing like that.
    very importent it will be Recursion and without any loops.
    thanks!

    Code:
     void scanMatrix(int matrix[][18],int indexRow, int indexCol, int sizeRow, int sizeCol){
    
    	int num;
    
    	if(indexCol == sizeCol && indexRow == sizeRow) return;
    
    	matrix[indexRow][indexCol]=scanf("%d",&num);
    
    	if(indexCol != sizeCol)
    		return scanMatrix(matrix,indexRow,indexCol+1,sizeRow,sizeCol);
    
    	if(indexCol == sizeCol)
    		return scanMatrix(matrix,indexRow+1,indexCol,sizeRow,sizeCol);
    }

    What exactly are you expecting to happen here?

    scanf is going to return -1 (aka EOF), 0 or 1.
    The successful input in num is just thrown away.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
