Question

So when I excute the program it's not showing anything. On the right is the file states.txt.

Is it my for loops thats giving me problems?

0 1-1 -1 -1 1 2-1 #includeci ostream> #include<fstream> #include-string> #includeionamp> using namespace std; write readTrans here to read in states.txt into the matrix // use generic argument names //AKA make this function here void readTransCint ar[10]05]) ifstream fin; fin.openC "states.txt 1-0; for(int 1 10; i++) for(int j = 0; j < 5; i++) fin ar[i]lj]: fin.closeO; write displayTrans here to display what is in the matrix //make sure it is easy to read and understand // make this function below void displayTrans (int ar 10][5]) for(int i = 0; 1 10; i++) for Cint j 0; j < 5; j++) cout << endl // The driver to read and display the matrix int mainO int myTrns[10]05]; readTrans myTrns); displayTrans(myTrns); matrix of state transitions

Answer 1

#include <iostream>
#include <string>
#include<fstream>
#include<iomanip>
using namespace std;

void readTrans(int a[10][4])//size of data in file is 10x4
{
ifstream fin;
fin.open("states.txt");
for(int i=0;i<10;i++)
for(int j=0;j<4;j++)
fin >> a[i][j];
fin.close();
}

void displayTrans(int a[10][4])
{
for(int i=0;i<10;i++)
{

for(int j = 0; j < 4; j++)
{
cout << setw(2) << a[i][j] << " ";//setw(2) used to properly align the data
}
cout << endl;
}
}

int main()
{
int a[10][4];
readTrans(a);
displayTrans(a);

}

You have declared the size of array wrongly. The dimensions should be 10x4 instead of 10x5 because there are only 4 columns hence dimension will be 10 x 4. Since you declares the dimensions more than the amount of data in the file, the program was still waiting for more data and that's why it wasn't showing any output. Use the above corrected code

Output on running the above code:

Process returned (8x0) Press any key to continue. execution time .250 s 1

Please give this solution a thumbs up if you find it helpful and comment if you have any doubts in it.
