Convert String into Binary Sequence

Given a string of character the task is to convert each character of a string into the equivalent binary number.
Examples :
Input : GFG Output : 1000111 1000110 1000111 Input : geeks Output : 1100111 1100101 1100101 1101011 1110011
The idea is to first calculate the length of the string as n and then run a loop n times. In each iteration store ASCII value of character in variable val and then convert it into binary number and store result in array finally print the array in reverse order.
Implementation:
// C++ program to convert
// string into binary string
#include <bits/stdc++.h>
using namespace std;
// utility function
void strToBinary(string s)
{
int n = s.length();
for (int i = 0; i <= n; i++)
{
// convert each char to
// ASCII value
int val = int(s[i]);
// Convert ASCII value to binary
string bin = "";
while (val > 0)
{
(val % 2)? bin.push_back('1') :
bin.push_back('0');
val /= 2;
}
reverse(bin.begin(), bin.end());
cout << bin << " ";
}
}
// driver code
int main()
{
string s = "geeks";
strToBinary(s);
return 0;
}
// C++ program to convert
// string into binary string
using namespace std;
// utility function
void strToBinary(string s)
{
int n = s.length();
for (int i = 0; i <= n; i++)
{
// convert each char to
// ASCII value
int val = int(s[i]);
// Convert ASCII value to binary
string bin = "";
while (val > 0)
{
(val % 2)? bin.push_back('1') :
bin.push_back('0');
val /= 2;
}
reverse(bin.begin(), bin.end());
cout << bin << " ";
}
}
// driver code
int main()
{
string s = "geeks";
strToBinary(s);
return 0;
}

// Convert ASCII value to binary
String bin = "";
while (val > 0)
{
if (val % 2 == 1)
{
bin += '1';
}
else
bin += '0';
val /= 2;
}
bin = reverse(bin);
System.out.print(bin + " ");
}
}
