Character char type

In addition to the integer, the fundamental types in C- —k are single- and double-precision floating point (float and double respectively), boolean (bool) and character (char). Variables of the floating point types can hold numerical values with fractional components as well as very large numbers that are too big to be stored in a variable of type int ... 

Char—Predefined character type, ordered by code. (See Table 1-22 for two common code sets.)... 

A double can hold numbers to a higher precision (more significant figures) than can a float. A variable of type bool can hold the value true or the value false, both of which are keywords. Additionally, in C++, numerical values automatically evaluate to true or false, with any non-zero value evaluating to true and zero evaluating to false. A variable of type char can hold a single 8-bit ASCII character ... 

Typical nitrogen isotherms for activated chars derived from unwashed Kevlar (in this case, yam) are shown in Fig. 2(a). Both isotherms, and those not illustrated for woven and non-woven chars, are of Type I character and most also display a small hysteresis loop. The sample activated to the lowest burn-off (27.4%) of those studied exhibited low pressure hysteresis (Fig. 2(a)). Corresponding Og plots, constructed using the reference data of Carrott et al. (ref. 9), are depicted in Fig. 2(b). External surface areas and pore volumes have...
