Int to ASCII char and char to ASCII number | C++ - c++

Question

I must write short script which will change int to ASCII char and char to ASCII int. But i don't know how. I wrote this short code but something is wrong. I'm programming for half-year. Can someone write it working? It is my first time to use functions in c++
#include <iostream>
#include <conio.h>
using namespace std;
char toChar(int n) {
return n + '0';
}
int toInt(char c) {
return c - '0';
}
int main()
{
int number;
cout << "Int: ";
cin >> number;
cout << "ASCII: " << static_cast<char>(number);
getch();
return 0;
}

Answer 1

Thank You very much Guys, I have done it with shorter and working code.
#include <iostream>
using namespace std;
int main(){
int a=68;
cout<<char(a);
char c='D';
cout<<int(c);
return 0;
}

Answer 2

you could also use printf, so you don't need to create other function for converting the number.
int i = 64;
char c = 'a';
printf("number to ascii corresponding to %d is %c\n", i, i);
printf("ascii to number corresponding to %c is %d\n", c, c);
the output is gonna be
number to ascii corresponding to 64 is A
ascii to number corresponding to a is 97

Answer 3

May be you could start with the code below. If this is incomplete, could you please complete your question with test cases?
#include <iostream>
using namespace std;
char toChar(int n)
{ //you should test here the number shall be ranging from 0 to 127
return (char)n;
}
int toInt(char c)
{
return (int)c;
}
int main()
{
int number = 97;
cout << "number to ascii corresponding to " << number << " is " <<(char)number << " or " << toChar(number) <<endl;
char car='H';
cout << "ascii to number corresponding to " << car << " is " << (int)car << " or " << toInt(car) << endl;
return 0;
}
The output is:
number to ascii corresponding to 97 is a or a
ascii to number corresponding to H is 72 or 72

Answer 4

#include <iostream>
using namespace std;
char toChar(int n)
{
if (n > 127 || n < 0)
return 0;
return (char)n;
}
int toInt(char c)
{
return (int)c;
}
int main()
{
int number = 97;
cout << "char corresponding to number " << number << " is '" << toChar(number) << "'\n";
char car='H';
cout << "number corresponding to char '" << car << "' is " << toInt(car) << "\n";
return 0;
}
output:
char corresponding to number 97 is 'a'
number corresponding to char 'H' is 72'
Originally I thought you were just looking to convert the number:
You can simply add and substract '0', to char and from char:
char toChar(int n) {
return n + '0';
}
int toInt(char c) {
return c - '0';
}
If you just want to cast the type, read this
