Question

Write a C++ console application that reverses an array of characters, and counts the number of:

          Lower case characters (islower)

          Upper case characters (isupper)

          Digits (isdigit)

          Other (not one of previous)

Create four global variables to hold these counts. Create function void count(char input[], char reverse[]) that takes as input two arrays: one that contains characters and another that will contain the reverse of that array. The function will reverse the input array and do the counts. In the main function, prompt for and get from the user a string and store it in the input array. You can assume the length of the array is less than 50. Function cin.getline can read characters into a char array. Call function count and then print the resulting counts.

Example input: AaBbCc123!@#

Output:

          Lowercase: 3

          Uppercase: 3

          Digits: 3

          Other: 3

Reversed array: #@!321cCbBaA

Answer 1

#include <iostream>
using namespace std;
int lowercase=0,upper=0,digits=0,others=0;

void count(char input[], char rev[]){
int length=0;
for(int i=0;input[i]!='\0';i++){
length++;
if(isupper(input[i]))
upper++;
else if(islower(input[i]))
lowercase++;
else if(isdigit(input[i]))
digits++;
else
others++;
}
int i,j;
for(i=0,j=length-1;i<length;i++,j--)
rev[i]=input[j];
rev[i]='\0';
}
int main()
{
char str[50],rev[50];
cout<<"Enter string : ";
cin.getline(str, 50);
count(str,rev);
cout<<"Lowercase: "<<lowercase<<endl;
cout<<"Uppercase: "<<upper<<endl;
cout<<"Digits : "<<digits<<endl;
cout<<"Other: "<<others<<endl;
cout<<"Reversed array: "<<rev<<endl;
return 0;
}
