    newbie array question

    I think I am having trouble converting a floating number into a character array. Can someone please help me with fixing the line I have commented. Thankyou.

    Code:
    float top;
    char price[5];
    
    printf("Enter top price");
    scanf("%f", &top);
    
    price = top;  // this line is probably wrong
    
    printf(price[0]);
    printf(price[1]);
    printf(price[2]);
    printf(price[3]);
    printf(price[4]);

    Use sprintf.
    7. It is easier to write an incorrect program than understand a correct one.
    40. There are two ways to write error-free programs; only the third one works.*

    Code:
    printf(price[0]);
    printf(price[1]);
    printf(price[2]);
    printf(price[3]);
    printf(price[4]);
    Those are all wrong also. The first argument to printf() needs to be a string, not a character.
    If you understand what you're doing, you're not learning anything.

    Code:
    float top;
    float price[5];
    
    printf("Enter top price");
    for(int i=0;i<5;i++){
    
    scanf("%f",&top);
     price[i]=top;
      printf("%f",price[i]);
    I hope this helps!
    }
