1.String “\\“ABC\“\\“ has a length of . A. 11 B. 7 C. 5 D. 3 Answer Explanation: The string constant consists of several characters, and the string length does not count ‘\0’ (the null terminator character), so in this question, \\ is one byte, \” is one byte, A is one byte, B is one … Read more
Statement: This is a personal learning record. Mathematical Knowledge: Gregory-Leibniz Formula Let x=1, we get Using the Gregory-Leibniz formula, to find the approximate value of π, we require the absolute value of the last term to be less than 10-6. [Example 1] Problem: Write a program to calculate and output the approximate value of π … Read more
# C Language Programming # According to the basic knowledge we have learned in C language programming, it is not difficult to implement each step separately. However, since we often need to use this repetitive design structure (known as a loop structure), C language provides loop statements to simplify and standardize loop structure programming. In … Read more

The C language also provides another way for multi-branch selection using the switch statement, which has the general form:switch(expression){ case constant_expression1: statement1; case constant_expression2: statement2; … case constant_expressionn: statementn; default: statementn+1;}The semantics are: calculate the value of the expression. Then compare it one by one with the subsequent constant expression values. When the value of … Read more
