how to pause for user input and continue the iteration of for loop

  arduino, arduino-ide, c++, loops

the for loop is not continuing after sending some thing via serial monitor
it stops at this is 0 but wont go to this is 1 , below is the simple code of what i’am trying to do

void setup() {
  // put your setup code here, to run once:


void loop() {
    for(int j=0;j<=5;j++){
        Serial.println("this is "+String(j));


it should print this is 0 wait for me to enter some thing via serial and continue to next iteration i.e this is 1 and again wait for me to allow it to iterate to next value . thanks for taking your time to help me
