How to read a string and assing it to an array

Question

hi guys, can you help me with this please, I have a char array and I need to pass it to a function like this
char str[100] = "11A";
toDeci(str, base);
And it works, but I want the user to be able to input a value and add it to the array like:
char str[100];
gets(str); // this way doesn't work and it is not recommended
toDeci(str);

Thanks😊

Answer 1

Victor_*, You can also go with the string data-type ;)

#include <iostream>

int main() {
std::string str;
std::cin >> str; // input the string
toDeci(str, base);

return 0;
}

PS:
Aidos Zhakupov, your code is correct if the length of string is known!

Answer 2

std::string

Use the string class and then you can use strcat(s1, s2) or s1 + s2 to concatenate the string together.

Answer 3

thanks it worked with cin.😃

Answer 4

I see that you use
string str;

I need my str to be an array (str[]) because my function waits for an array, what's the difference between char str[] and string str??

Answer 5

Victor_* you pass a string without using an array. After the user enters a value, it passes the value to the method. This method is sometimes useful and simple.

Rahul Ahah yes. I know C ++ a little bit and wrote by analogy Java). In Java, for example, you could use arr.length☺️
