What is the output of

printf("a = %05d\n", 35);

You should first think about this and try to figure out the answer by hand. Then feel free to use the window below to write a program to verify your answer. This time you have to write the entire program by yourself (hint: get started by copying and pasting from a previous program.)

admin.....open in new window

a = 00035
Correct
35

What happens when you use the format specifier %f to print out an integer? (feel free to write a short C program to try this out).
