Hola, si eres nuevo en C++ no parece un problema sencillo para alguien que esté empezando porque hay que manejar varios conceptos al mismo tiempo
Un ejemplo de texto que se mueve es este:
#include<iostream>
#include<unistd.h>
#include<stdlib.h>
#include<string>
#include<vector>
using namespace std;
void moveText();
void tailName();
void tailArrow();
void showTimes();
void userString();
void setSpeed();
void display();
void dispMenu();
int index1 , index2, index3, counter1, counter2, counter3, textT, size, speed;
string Name[78], tempString[78], Right[78], Left[78];
vector<string> temp_userString;
int main()
{
int userChoice;
do{
dispMenu();
cin >> userChoice;
switch(userChoice){
case 1:
system("cls");
moveText();
tailName();
tailArrow();
showTimes();
userString();
display();
break;
case 2:
system("cls");
setSpeed();
break;
case 3:
system("cls");
break;
case 0:
system("cls");
cout << "You exited the program." << endl;
break;
default:
system("cls");
cout << "Error: Undefind choice." << endl;
break;
}
}while(userChoice != 0);
return 0;
}
void dispMenu(){
cout << "=======================" << endl;
cout << "Enter 0 to exit." << endl;
cout << "Enter 1 to start." << endl;
cout << "Enter 2 set speed." << endl;
cout << "Enter 3 to clear screen." << endl;
cout << "Your choice: ";
}
void moveText()
{
size = 78;
counter1 = 0;
counter2 = 0;
counter3 = 0;
speed = 130000;
}
void setSpeed(){
int tempSpeed;
cout << "Enter 0 for default." << endl;
cout << "Enter 1 for fast." << endl;
cout << "Enter 2 for middle." << endl;
cout << "Enter 3 for slow." << endl;
cin >> tempSpeed;
system("cls");
switch(tempSpeed){
case 1:
speed = 70000;
break;
case 2:

break;

break;
