How to get the first character of a string in C++
In this post we will give you information about How to get the first character of a string in C++. Hear we will give you detail about How to get the first character of a string in C++And how to use it also give you demo for it if it is necessary.
we are going to learn about different ways to get the first character of a string in C++.
Consider, we have the following string.
string car = "audi";
Now, we want to get the first character a from the above string.
Getting the first character
To access the first character of a string, we can use the subscript operator [ ] by passing an index 0.
Here is an example, that gets the first character a:
#include <iostream>#include <string.h>using namespace std;int main(){ string car = "audi"; char firstCharacter= car[0]; cout<< firstCharacter; return 0;}Output:
"s"
Note: In C++ Strings are a sequence of characters, so the first character index is 0 and the second character index is 1, etc.
Similarly, we can use the built-in front() function in C++ to get the first character of a string.
#include <iostream>#include <string.h>using namespace std;int main(){ string car = "audi"; char firstCharacter= car.front(); cout<< firstCharacter; return 0;}We can also use the at() function to get the first character like this.
#include <iostream>#include <string.h>using namespace std;int main(){ string car = "audi"; char firstCharacter= car.at(0); cout<< firstCharacter; return 0;}In the code above, we have passed the first character index 0 to the at() function.
