Objectives

Learn how to use the sizeof$()$ operator for various basic C data types.

More practice with a makefile.

Write a C program $($called sizeof.c$)$ that uses the sizeof$()$ operator to print the number of bytes and number of bits the required for basic C data types on the ada server. Write a makefile to compile the C file. Show the number of bytes and bits required for the following C data types:

char

short

int

long

float

double

long double

void $*$

The output from your program should look like this:

rchaney # $./$sizeof

Size of basic C data types

$$ sizeof$($char$)1$ byte $8$ bits

$$ sizeof$($short$)2$ bytes $16$ bits

$$ sizeof$($int$)4$ bytes $32$ bits

$$ sizeof$($long$)8$ bytes $64$ bits

$$ sizeof$($float$)4$ bytes $32$ bits

$$ sizeof$($double$)8$ bytes $64$ bits

$$ sizeof$($long double$)16$ bytes $128$ bits

$$ sizeof$($void $*)8$ bytes $64$ bits

The CFLAGS and LDFLAGS variables in the makefile should use these:

CFLAGS $=-$g$3-$Wall $-$Werror $-$std$=$c$11-$pedantic

LDFLAGS $=-$lm $-$no$-$pie
