Copy contents of non null terminated char array into another char array

问题

I have an array of structs, each struct has a char array and an int.

typedef struct {
    int id; //Each struct has an id
    char input[80]; //Each struct has a char array
    } inpstruct;

inpstruct history[10]; //Array of structs is created

I have another char array that contains the user's input

char inputBuffer[80];

The user enters a word followed by the \n character. For example, inputBuffer will contain 3 chars: 'l' 's' '\n'.

I want to copy all the chars in inputBuffer into history[index].input

I have tried using:

strcpy(history[index].input, inputBuffer);

But since inputBuffer is not null terminated it does not work. How can I copy all the chars from inputBuffer into history[index].input ?

回答1:

You want to memcpy

memcpy(history[index].input, inputBuffer, sizeof(inputBuffer)*sizeof(inputBuffer[0]));
