int array to char array

[gohawks]

How would I convert an int array to a char array? Basically, instead of it printing a value, i was s3 to be "D", s2 to be "V" and s1 to be "H"

  void initMatrix(int m[SIZE][SIZE], string s1, string s2, int gap)
{
    int r,c; // ROW and COLUMN
    int numRows;
    int numCols;
    int gapscore = -2;
    int vals1 =0;
    int vals2 =0;
    int vals3 = 0;
    int maxscore =0;
    int scoret;
    
    
    
    
    
    // plus 1 because matrix has extra row/column
    numRows = s1.length() + 1;
    numCols = s2.length() + 1;
    
    m[0][0]= 0;  // initialize the value at (0,0) to 0
    
    // initialize first row
    
    for(r=1;r<numRows;r++)
    {
        m[r][0] = gap * r;
    }
    
    // initialize first column
    for(c=1;c<numCols;c++)
    {
        m[0][c] = gap * c;
    }
    
    // Initialize the rest of the matrix...
    
    for(int a=1;a<numRows;a++)
    {
        vals2 = (m [(a-1)][0] + gapscore );
        m[a][0] = vals2;
    }
    
    for(int b=1;b<numCols;b++)
    {
        vals1 =(m[0][(b-1)] + gapscore);
        m[0][b] = vals1;
        
    }
    for(int a=1;a<numRows;a++)
    {
        for(int b=1;b<numCols;b++)
        {
            scoret= score(s1[a],s2[b]);
            vals3= scoret + m[(a-1)][(b-1)];
            vals2 = (m[(a-1)][b]+ gapscore);
            vals1= (m[a][(b-1)] + gapscore);
            
            maxscore = vals3;
            
            if (maxscore < vals1)
            {
                maxscore =vals1;
            }
            if(maxscore < vals2)
            {
                maxscore = vals2;
            }
            m[a][b] = maxscore;
        }}
    
    cout<<"The total score is "<<maxscore<<endl;

You can apply an ASCII value to an int, say

int x = 65;

Then you assign the value stored in memory to a char
char ch = x;
A
Then
cout << ch << endl;
would print

A

It works the other way around also.

What if I couldn't assign a specific value to the integer, since it is based on an specific input? Is there a way to convert a matrix of numbers into a matrix of letters?

You could loop over the data and convert,
OR you could cast it.

int main()
{
  int x = 65;
  char ch = 'A';

  cout << (char *) &x << endl;
  cout << (int ) ch << endl;
  
}
