Codex (i) of C + + learning

For the sake of need, I have recently studied C + +. A simple familiarity with this language that I have forgotten for years. As a study, record here. The difference between C and C + + is also compared.

Code for C:

#include <stdio.h>
#include <stdlib.h>

/**
　*　 定义一个结构体
　*/
struct Location {
　　　 int x; // 横坐标
　　　 int y; // 纵坐标
} location;

int main(void) {
　　　 printf("输入X坐标：\t\n");

　　　 int x;
　　　 scanf("%d", &x);

　　　 location.x = x;

　　　 printf("输入Y坐标：\t\n");

　　　 int y;
　　　 scanf("%d", &y);
　　　 location.y = y;

　　　 printf("X坐标是：\t%d\n", location.x);
　　　 printf("Y坐标是：\t%d\n", location.y);

　　　 //　 做倒三角打印
　　　 int i;

　　　 for (i = 0; i < y; i++) {
　　　　　　　 printf("%d\t", i + 1);

　　　　　　　 int j;
　　　　　　　 for (j = i; j < x; j++) {
　　　　　　　　　　　 printf("* ");
　　　　　　　 }
　　　　　　　 printf("\n");
　　　 }

　　　 return EXIT_SUCCESS;
}

This uses the structure body location and generates an instance location. Enter numbers by scanf to X and Y. Assigns a value to the variable x of the struct location in location.x = x; Thus we can see that the structure is the object-oriented foundation, especially the predecessor of the data object.
