many programming languages borrow heavily form c language, including c , c# .
one of c’s advantages is efficiency. because c was intended for applications where assembly language had traditionally been used, it was crucial that c programs could run quickly and in limited amounts of memory.
c’s weaknesses arise from the same source as many of its strengths: c’s closeness to the machine.
which of the following is a legal c identifier?
which of the following is not keyword in c language?
which of the following is not a constant in c language?
which of the following is not a float constant in c language?

suppose that we call scanf as follows: scanf(“%f%d%f”, &x, &i, &y); if the user enters: 12.3 45.6 789 what will be the values of x, i, and y after the call? (assume that x and y are float variables and i is an int variable. ↙ is used to represent enter key)
which one of the following is correct?

c compilers are required to check that the number of conversion specifications in a format string matches the number of output items.
if the format string is “%d\n”, scanf will skip white space, read an integer, and then skip to the next non-white-space character. so a format string like this can cause an interactive program to “hang” until the user enters a nonblank character.
