I have used CodeBlocks compiler for debugging purpose. But you can use any C++ programming language compiler as per your availability.
C++: Count Alphabets Digits Special Character In String
#include <iostream>
#include <string.h>
#define MAX_SIZE 100 //Maximum size of the string
using namespace std;
int main()
{
char string[MAX_SIZE];
int alphabets, digits, specialchars, i;
alphabets = digits = specialchars = i = 0;
cout<<"Enter any string: ";
cin>>string;
while(string[i]!='\0')
{
if((string[i]>='a' && string[i]<='z') || (string[i]>='A' && string[i]<='Z'))
{
alphabets++;
}
else if(string[i]>='0' && string[i]<='9')
{
digits++;
}
else
{
specialchars++;
}
i++;
}
cout<<"Total Alphabets: "<<alphabets<<endl;
cout<<"Total Digits: "<<digits<<endl;
cout<<"Total Special characters: "<<specialchars<<endl;
}
Result
