Need help decoding a string
Sep 20, 2015 at 4:21am UTC
For my program, I am currently trying to figure out how to determine the length of the string the user imputed. The string must be nine characters long and the function needs to return a true of false based on the string length. Here is what I have so far for my project.
A little background on my program.
For this program I am taking in a nine character string and decoding them into three separate sets and summing their ascii values.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52

bool decode(string code, int &codeA, int &codeB, int &codeC);
int main()
{
int x, y, z;
string sequence;
cout << "Enter a sequence to decode " << endl;
cin >> sequence;
decode(sequence, x, y, z);
if (bool decode = false )
{
cout << "Sequence was invalid" << endl;
}
else
{
cout << "Your sequence decoded is " << endl;
cout << "Num 1 = " << x << endl;
cout << "Num 2 = " << y << endl;
cout << "Num 3 = " << z << endl;
}
return 0;
}
bool decode(string code, int &codeA, int &codeB, int &codeC)
{
codeA = 0;
codeB = 0;
codeC = 0;
bool codelength;
if (code != '9' )
{
codelength = false ;
}
else
{
}
return codelength;
}

You'll have to modify for your function
1 2 3 4 5 6 7 8
if (sequence.size()!= 9)
{
return 1;
}
else
{
return 0;
}

In
bool decode(string code, int &codeA, int &codeB, int &codeC)
use
code.size();
to get the size of the string parameter
code . For more string methods see here:
http://www.cplusplus.com/reference/string/string/
You cannot do this:
if (code != '9' )
code is a string object and '9' is a char literal. This is a type mismatch.

Thank you so much for the help. Another question I have is, how would I change 0 and 1 to (true or false)

1 2 3 4 5 6 7 8
if (sequence.size()!= 9)
{
return true ;
}
else
{
return false ;
}
