如何使 printf 在循环中只运行一次

Question

How to let printf run only once in loop, the P is argv so it will print Guess 4 times if the value of P is 4

while (h!=P) {
 for (int i=0;i<P;i++)
     { 
     n[i]=1,j[i]=1;
     printf("\nGuess:");
     scanf("%d",&guess[i]);
     }

Output example

1 3 4 1
Guess:1 3 4 1

Guess:
Guess:
Guess:
4H0X
correct

1 4 1 2
Guess:4 1 2 1

Guess:
Guess:
Guess:
0H4X
Guess:

Answer 1

If you wnat only one "Guess" per for loop:

for (int i=0;i<P;i++) {
    ...
    if (i == 0)
        printf("\nGuess:");
    ...
    }

Answer 2

 while (h!=P) {
 printf("\nGuess:");
 for (int i=0;i<P;i++)
 { 
 n[i]=1,j[i]=1;

 scanf("%d",&guess[i]);
 }

I think just by putting that printf out from the FOR you can make it
