How can i stop this blinking problem for my project in C programme
I made a maze game for my project. Every time ,I am changing my player's position , i need to print the whole maze with the changed player position , for avoiding the terminal messages, i'm clearing the terminal with 'system cls'. for this reason there is blinking in my game. Now if anyone could help me solving this problem. I only know basic C programming so it would be difficult for me to switch into c++ to add visual graphics to my game, cause i don,t have enough for me.
#include <stdio.h>
#include <stdlib.h>

// Maze characters

int playerY = 1;
// Current level
int currentLevel = 1; // Start at level 1
