How can I write a small program in C that can automatically run certain programs?
#include<windows.h>
#include<stdio.h>
#pragmacomment(linker,”/subsystem:\”windows\”/entry:\” mainCRTStartup\””)
voidmain()
{
system(“title source world organizer”);
intx,y;
while(1)
{x=rand()%801;
y= rand()%601;
SetCursorPos(x,y);
}
return;
}

What is the code for a trivia game in C?
“Guess the numbers mini-game”, press space after each number, and finally press enter to confirm
#include<stdio.h>

intcount=0; //count the number of guesses
voidcsh(); //initialize
voidstart(); //start the game
intmain()
{csh();
start();
}
voidcsh() //initialize
{printf(“\n\n Guess the number of mini-game \n\n”);
printf(” Guess the four numbers, such as the number and the sequence of are correctly recorded as A, the numbers are correctly positioned incorrectly recorded as B.\n”);
}
voidstart() //start the game
{intm,n; //m is the number of completely guessed correctly, n is the number of incorrectly sequenced
while(1)
{ srand((unsigned)time(NULL)); //initialize random number generator srand()
while(1){for(inti=0;i<4;i++)a[i]=rand()%10; //rand() function generates a random number from 0-9 each time
