Question

Using C++ programming. Write a program that takes a string of input from the user and separates the string of words based on the premise that the string contains words whose first letter is uppercase. Then, display the phrase (or sentence) to a string in which the words are separated by spaces and only the first word of the phrase starts with an uppercase letter. For example, if the user enters "IAmTheTeacher", then the program would display: "I am the teacher" on the screen.

Answer 1

Program:

#include<iostream>
using namespace std;

int main()
{
string str,outputStr;
int i;

cout<<"Enter a string: ";
cin>>str;

for(i=0;i<str.length();i++)
{
if(str[i]>='A' && str[i]<='Z')
{
if(i!=0)
outputStr=outputStr+" ";

outputStr=outputStr+str[i];
}
else
{
outputStr=outputStr+str[i];
}
}

cout<<outputStr;
return 0;
}

Output:

OR

#include<iostream>
using namespace std;

int main()
{
string str;
int i;

cout<<"Enter a string: ";
cin>>str;

cout<<"Output String: ";
for(i=0;i<str.length();i++)
{
if(str[i]>='A' && str[i]<='Z')
{
if(i!=0)
cout<<" ";

cout<<str[i];

}
else
{
cout<<str[i];
}
}

return 0;
}
