Question

Here is the code

       printf("\n");
       printf("Enter a integer vaule:");
       scanf("%d" , &num3);
       printf("You entered: %015d", num3);


       printf("Enter a float value:");
       scanf("%f", &deci3);
       printf("You entered: %15.2f", deci3);
       printf("\n");

the output is

       Enter a integer vaule:4.4
       You entered: 000000000000004
       Enter a float value:You entered:            0.40

The problem is this code is not stopping at

       printf("Enter a float value:");

and this scanf

      scanf("%f", &deci3);

seems to be getting its value from the previous scanf

Answer 1

The %d conversion stops wherever the integer stops, which is a decimal point. If you want to discard the input there, do so explicitly… getc in a loop, fgets, or such. This also allows you to validate the input. The program should probably complain about 4.4.
