1. Create a 2D array, A[10][10], of 100 integers.

2. Ask the user for two integers R and C where 0 < R ( 10 and 0 < C ( 10.

3. Using nested loops, fill every element A[j] (where 0 ( i < R and 0 ( j < C) with

random numbers ranging in [0, 200]. I will describe how to use the pseudorandom

number generator.

4. Using nested loops, print out every element A[j] (where 0 ( i < R and 0 ( j < C)

2. Relevant equations

Also notice that your program needs this number to be in the specified range of [0, 200].

Would mod again be useful here?

3. The attempt at a solution

So, I'm pretty confident that I have the array filled properly, to the extent of inputing random numbers in each element of the array "A". However, the range is waaaay off, I think the pseudo-random number generator's range is from 0 to 2147483647. I need to cut that back to [0,200]. Any tips on how to approach that using what I'm assuming is being referred to as mod (%)?Code (Text):

#include <iostream>

#include <ctime>

#include <cstdlib>

using namespace std;

int main()

{

srand(time(NULL)); //Seed Random Number Generator

int A[10][10];

int R;

int C;

cout<<"Please Enter an integer between 1 and 10: \n"; // Ask for Values of R and C, ensuring both within specified range

cin>>R;

while (R<1 || R>10)

{

cout<<"Please Re-enter an integer between 1 and 10: \n";

cin>>R;

}

cout<<"Please Enter another integer between 1 and 10: \n";

cin>>C;

while (C<1 || C>10)

{

cout<<"Please Re-enter an integer between 1 and 10: \n";

cin>>C;

}

for(int i=0; i<=R; i++) //Nested for loops to fill array with random numbers

{

for(int j=0; j<=C; j++)

{

A[i][j]=rand();

}

}

return 0;

}

Secondly, to output every element of A in the specified range, would I use a linear search, if so, how would I go about taking the found value and outputting it rather than just returning that it was found?

Thanks for any help!
