Day 4: Arrays and Strings

Array

 

• fixed number of elements of the same type stored sequentially in memory
• initialization, or unexpected results
• arrays are passed by reference
• multidimensional arrays are merely an abstraction for programmers, as all the elements in the array are sequential in memory

 

String

 

• simply a character array and can be manipulated as such
• char hello[] = {'h','e','l','l','o','\0',}
• char hello = "hello"

#include <iostream>
  #include <cstring>
  using namespace std;

  int main() {
  char fragment1[] = "I'm a s";
  char fragment2[] = "tring!";
  char fragment3[20];
  char finalString[20] = "";

  strcpy(fragment3, fragment1);
  strcat(finalString, fragment3);
  strcat(finalString, fragment2);

  cout << finalString;
  return 0;
 }
