PROGRAM:C++ Program to Find the Frequency of Characters in a String
/* C++ Program to Find the Frequency of Characters in a String*/
1.Find Frequency of Characters of a String Object
#include <iostream>
using namespace std;
int main()
{
string str = “C++ Programming is awesome”;
char checkCharacter = ‘a’;
int count = 0;
for (int i = 0; i < str.size(); i++)
{
if (str[i] == checkCharacter)
{
++ count;
}
}
cout << “Number of ” << checkCharacter << ” = ” << count;
return 0;
}
2: Find Frequency of Characters in a C-style String
#include <iostream>
using namespace std;
int main()
{
char c[] = “C++ programming is not easy.”, check = ‘m’;
int count = 0;
for(int i = 0; c[i] != ‘\0’; ++i)
{
if(check == c[i])
++count;
}
cout << “Frequency of ” << check << ” = ” << count;
return 0;
}
