How to move cursor back to the first line in C?

问题:

I am new to C and this is my code.

#include<stdio.h>

void printCard(char name, char symbol);

int main()
{
    printCard('J','*');
    printCard('K','&');  
}
void printCard(char name, char symbol)
{
    printf("-------------\n");
    printf("| %c         |\n",name);
    printf("| %c         |\n",symbol);
    printf("|           |\n");
    printf("|           |\n");
    printf("|           |\n");
    printf("|         %c |\n",symbol);
    printf("|         %c |\n",name);
    printf("-------------\n");
}

This is the output that I am getting.

Is there a way to get that second card to appear beside the first? Thanks

If your terminal supports them, these terminal escape codes could be use to position the cursor.

#include<stdio.h>

void printCard( int col, char name, char symbol);

int main()
{
    printf ( "\033[2J");//clear screen
    printCard( 0, 'J','*');
    printCard( 1, 'K','&');
    return 0;
}
void printCard(int col, char name, char symbol)
{
    printf ( "\033[1;%dH", col * 14);//move cursor line 1
    printf("-------------\n");
    printf ( "\033[2;%dH", col * 14);//move cursor line 2
    printf("| %c         |\n",name);
    printf ( "\033[3;%dH", col * 14);//move cursor line 3
    printf("| %c         |\n",symbol);
    printf ( "\033[4;%dH", col * 14);//move cursor line 4
    printf("|           |\n");
    printf ( "\033[5;%dH", col * 14);//move cursor line 5
    printf("|           |\n");
    printf ( "\033[6;%dH", col * 14);//move cursor line 6
    printf("|           |\n");
    printf ( "\033[7;%dH", col * 14);//move cursor line 7
    printf("|         %c |\n",symbol);
    printf ( "\033[8;%dH", col * 14);//move cursor line 8
    printf("|         %c |\n",name);
    printf ( "\033[9;%dH", col * 14);//move cursor line 9
    printf("-------------\n");
}

This was the function that worked for me.

void gotoXY(int x, int y)
{

 COORD coord;

 coord.X = x;

 coord.Y = y;

 SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), coord);

}

Thanks @PCLuddite for pointing me to check setConsoleCursorPosition which helped me find this above function online. Hope this helps others.
