Final answer:
To solve this problem, define a function called CountCharacters that takes a character and a string as input. The function should iterate through the string and count how many times the character appears. Return the count as the output. You can call this function in your main program to get the desired output.
Step-by-step explanation:
To solve this problem, you can define a function called CountCharacters that takes two parameters: a character (userChar) and a string. The function should iterate through each character in the string and compare it with the input character. If they match, a counter should be incremented. At the end, the function should return the value of the counter.
Here's an example implementation:
int CountCharacters(char userChar, const string inputString) {
int count = 0;
for (int i = 0; i < inputString.length(); i++) {
if (inputString[i] == userChar) {
count++;
}
}
return count;
}
You can call this function in your main program by passing the input character and string as arguments:
char userChar;
string inputString;
// Prompt the user for input
cout << "Enter a character: ";
cin >> userChar;
cout << "Enter a string: ";
cin.ignore();
getline(cin, inputString);
// Call the CountCharacters function
int result = CountCharacters(userChar, inputString);
cout << "The character '" << userChar << "' appears " << result << " times in the string." << endl;
This program first prompts the user to enter a character and a string. Then, it calls the CountCharacters function and stores the result in the variable 'result'. Finally, it prints out the number of times the character appears in the string.
