I have been looking up examples and tutorials on how to make strlen work, but nothing is working. I am making a small program that lets you type your sentence and you can search a specific letter in the sentence.
The error reads:
19:23: error: cannot convert âstd::string {aka std::basic_string<char>}â to âconst char*â for argument â1â to âsize_t strlen(const char*)â
#include <iostream>
#include <string>
#include <cstring>
using namespace std;
int main() {
char letter;
string sentence;
int count;
cout << "Enter a character to count the number of times it is in a sentence: ";
cin >> letter;
cout << "Enter a sentence and to search for a specified character: " << endl;
getline(cin, sentence);
for(int i = 0; i < strlen(sentence); i++){
if(sentence[i] == letter){
count++;
}
}
cout << letter << " was found " << count << " times." << endl;
}
Since
sentence
is astd::string
, you should use eithersentence.length()
orstrlen(sentence.c_str())
.
