I need help with this code because I have created three functions
But the hexToInt function is not converting correctly, it only works if the hex is an integer type 19 and not A or 1D.
and the toUpper and toLower functions do not print a letter with an accent
toUper it after the data as follows below:
MY NAME is C ++ that is, it does not print the capital letter the same is said for the toLower function below:
My name is c ++
The code is this below:
#include <iostream>
#include <sstream>
#include <cctype>
#include <cstring>
#include <cstdio>
std::string toLower(std::string s)
{
for (unsigned int i = 0; i < s.size(); i++)
s[i] = towlower(s[i]);
return s;
}
std::string toUpper(std::string s)
{
for (unsigned int i = 0; i < s.size(); i++)
s[i] = towupper(s[i]);
return s;
}
int hexToInt(std::string s)
{
int res = 0;
for (size_t i = 0; i < s.size(); i++) {
int multiplier = 1;
int exp = (s.size() - 1 - i);
while (exp-- > 0)
multiplier *= 16;
int ch = s[i];
if (ch >= '0' && ch <= '9')
res += multiplier * (ch - '0');
else if (ch >= 'a' && ch <= 'z')
res += multiplier * (ch - 'a');
else if (ch >= 'A' && ch <= 'Z')
res += multiplier * (ch - 'A');
}
return res;
}
int main () {
std::cout<<"\n\n\thexToInt{0}: "<<hexToInt("0");
