False - this is false because they are enclosed in single quotes not double.
A character constant is enclosed in double quotes.
True
A literal constant is an unnamed constant used to specify data.
False
A precision modifier may be used for the output of any numeric value.
True
All code found in the executable statement and local declaration sections of the main function is considered to be the body of the function.
True
Comments are added to a program to improve its level of documentation intended for other programmers.
True
Each variable in a C program must be declared and defined before it can be used.
True
Every program must have exactly one function named main.
True
It is much easier to find and work with variables if they are defined in separate lines.
True
The address list of a scanf function must specify where in the memory of the computer the input should be stored.
True
The backslash (\) is known as an escape landscape.
True
The command to create a defined constant is usually placed at the beginning of the program.
True
The conversion code selected for a placeholder (conversion specification) depends on the data type of the value to be displayed in a printf statement.
False
The declaration section contains executable instructions for the computer.
True
The file <stdio.h> and <math.h> are libraries that contain standard functions for our use.
True
The gcc compiler as found on guru will require that the main be an int (integer) function.
True
The gcc compiler as found on guru will require the source code file name to end with a .c extension.
True
The main function is the starting point for execution of the program.
True
The preprocessor is a part of the compiling process and prepares your code for the remainder of the process.
True
The return (0); statement will be the final statement in the main function.
True
The return statement in main will return control to the operating system and terminate the current program.
False
The size modifier is used to specify the minimum number of positions to reserve for the output of a value.
True
The width modifier for the output of a value must be large enough to account for the integral value of the number, the decimal point, and the number of digits in the decimal position.
True
Variable declarations will NEVER be permitted in the global section this semester.
True
Variables are named memory locations that have a type.
True
Variables in the C language are initialized automatically when they are defined.
True
While variables have data types, constants (both literal and defined) do not.
True
Within each function the local declarations and executable statements must NOT be permitted to overlap.
