Objectives To write C++programs to perform simple calculations (2.2). To read input from the keyboard using the cin object($2.3). To simplify programming by omitting the std::prefix (2.4). To use identifiers to name variables,constants,functions,and classes (2.5). To use variables to store data(§§2.6-2.7). To program with assignment statements and assignment expressions (2.7) To use constants to store permanent data($2.8). To declare variables using numeric data types($2.9). To use operators to write numeric expressions (2.9). To convert numbers to a different type using casting (2.10). To represent character using the char type (2.11). To become familiar with C++documentation,programming style,and naming conventions(§2.l3). To distinguish syntax errors,runtime errors,and logic errors($2.14) 。 To debug logic errors (2.15).Objectives Objectives • To write C++ programs to perform simple calculations (§2.2). • To read input from the keyboard using the cin object (§2.3). • To simplify programming by omitting the std:: prefix (§2.4). • To use identifiers to name variables, constants, functions, and classes (§2.5). • To use variables to store data (§§2.6-2.7). • To program with assignment statements and assignment expressions (§2.7). • To use constants to store permanent data (§2.8). • To declare variables using numeric data types (§2.9). • To use operators to write numeric expressions (§2.9). • To convert numbers to a different type using casting (§2.10). • To represent character using the char type (§2.11). • To become familiar with C++ documentation, programming style, and naming conventions (§2.13). • To distinguish syntax errors, runtime errors, and logic errors (§2.14). • To debug logic errors (§2.15)
