ANSI C by E. Balagurusamy chapter ONE solution
1) State whether the following statements are true or false.
a)
Every line in a C
program should end with a semicolon (True)
b) The closing brace of the main( ) in a program is the logical end of the program (True)
c) Comments cause the computer to print the text enclosed between /* and */ when executed (F)
d) Every C program ends with an END word (False)
e) A printf statement can generate only one line of output (false)
f) The purpose of the header file such as stdio.h is to store the source code of a program (True)
g) A line in a program may have more than one statement (False)
h)Syntax errors will be detected by the compiler (True)
i) In C language lowercase letters are significant (True)
j) main( ) is where the program begins its execution (True)
