[C] Implementation Method for printing the diamond pattern and printing the diamond pattern

[C] Implementation Method for printing the diamond pattern and printing the diamond pattern

Method 1: Split the diamond into two parts and print the content above and below in sequence.

Source code:

#include<stdio.h>
Int main()
{
     / / First write the upper part of the diamond
     Int line = 0;
     Printf ("Please enter the number of lines");
     Scanf("%d",&line);
     / / According to the pattern, to output the upper part of the diamond, you need to use the for loop, loop output line output each line
     //on
     Int i = 0;
     For(i=0;i<line;i++){
         / / Each line first outputs a space, and then output *
         Int j = 0;
         / / Output space
         For(j=0;j<line+1-i;j++){
             Printf(" ");
         }
         //output*
         For(j=0;j<2*i-1;j++){
             Printf("*");
         }
         Printf("\n");
     }
     //under
     For(i=0;i<line-1;i++){
         Int j = 0;
         For(j=0;j<i+1;j++){
             Printf(" ");
         }
         For(j=0;j<2*(line-1-i)-1;j++){
             Printf("*");
         }
         Printf("\n");
     }
     Return 0;
}
