Can anyone help me with this C++ program?

I need help writing a simple program in "C". Can anyone help? Please see details.?

• I need to write a program that prompts the user to enter a floating-point number. The program will then print the number entered, first in decimal-point notation and then in exponential notation. Have the output use the following format: The input is 21.290000 or 2.129000e+001. Hint: %d or %i is used for integers, %f is used for floating point, %e is used for exponential notation PLEASE HELP ME....I AM LOST HERE!!!

• Answer:

  #include <stdio.h> int main () { float f; printf ("Enter a number: "); scanf ("%f", &f); printf ("The number in Decimal-point notation: %10.5f \n", f); printf ("The number in exponential notation: %e \n", f); } Hope this helps... the number between %...f (10.5) gives you field length. 10 is total field lenght (including . point) and 5 give number of digits after decimal.
