Brush questions in C language | output love (14) with putchar

example 14：C Language implementation successively outputs Love Four characters .

Their thinking ： Definition 4 A character variable , Assign initial values respectively L、o、v、e’, And then use putchar Output function 4 The value of a character variable .

Source code demo ：

#include<stdio.h>
int main()
{
  char character1,character2,character3,character4;// Defining character variables 
  character1='L';// Initialize variable , The character L Assign a value to character1
  character2='o';// Initialize variable , The character o Assign a value to character2
  character3='v';// Initialize variable , The character v Assign a value to character3
  character4='e';// Initialize variable , The character e Assign a value to character3
  putchar(character1);// The output characters L
  putchar(character2);// The output characters o
  putchar(character3);// The output characters v
  putchar(character4);// The output characters e
  putchar('\n');// Line break 
  return 0;// The return value of the function is 0
}

Compilation result ：
