C For Dummies Blog

Though it’s shunned today, using a union in your C code was common in the 1980s.

A C language keyword worthy of shunning is union.

Continuing from last week’s Lesson, I discovered that though the C language lets you create a Boolean array, the data is stored in char-sized integers and not true binary data.

This month’s Exercise is about finding the limits, or how large a signed or unsigned char value can get before it flips over to negative or to zero.

As a programmer well-versed in Assembly Language, I’m all too familiar with the bits that populate a byte.

Difficulty: ★ ★ ☆ ☆ The C language comes with a variety of data types that hold integer (whole number) values.

One of the weaknesses of the C language when measured against the newer, trendier programming languages is that it lacks a Boolean type.

Having two file descriptors available to access the same file might seem redundant.

One of C library functions I find most odd is dup().

The topic for this month’s Exercise is to code a recursive function that solves the Ramanujan Nested Radical, illustrated in Figure 1.

About six years ago, I wrote about opening a file in the raw.

Difficulty: ★ ★ ★ ★ Srinivasa Ramanujan was a mathematician of the genius variety in that he did amazing things in his short lifetime.

The for keyword opens the door to looping in C, as well as in other programming languages.
