Question 1
#include <stdio.h>

void draw(___ row, ___ column, ___ symbol){

	// declare local variables (to be used in the loop)
	// use nested loop to print
	// for each row
	//	for each column
	//		print symbol
	//	print link break

}
int main(){

        int col, row;
        char sym, temp;

	// enter row and col
        printf("Number of rows and columns = ");
        scanf("%d%d",&row, &col);

	// enter sym
        printf("Symbol = ");
        scanf("%c%c",&temp,&sym);

	// call draw function

        return 0;
}

Question 2
#include <stdio.h>

// the print function return 1 if x is a prime number
// return 0 if x is not a prime number
____ prime(___ x){
	
	// set isPrime to 1 at the beginning 
	// check every number i starting from 2 (up to what number?)
	// if the number is divisible by i 
	// 	set isPrime to 0 
	
        int isPrime=___, i=___;

        if(x==1)  // 1 is special case, why?
                return ____;
        else{  
		// while i is smaller than the biggest number and isPrime is still 1
                while(______________){
				// if x is divisible by i
                                if(__________)
                                        isPrime=____;
                                i++;
                }
        }

        return _____________;
}

int main(){

        int i, m, n;

	// enter m

	// enter n (check to ensure that n is larger than m

	// for all number from m to n
	//	if the number is a prime number (use prime function)
	//		print the number 
        

        return 0;
