1. Scope
1. This International Standard specifies the form of the C programming language and establishes an interpretation of programming in the C programming language. [Note: international standards are designed to improve the portability of C Programs in multiple data processing systems. Its purpose is to be used by implementers and programmers.] It specifies:
-- C language representation;

To get this topic, we will first think of using loops to complete.But not every operator is a "+" sign.Therefore, we are here to use (-1) of the I-side to do "+" "-" number control.The loop variable i is then treated as the denominator.Here we have the idea of the loop body is basically OK.It is important to note that the calculation results here are expressed in decimals, so it is not possible to define variables with int integers.The code is as foll
Note: When calculating 1 to use a double type that is 1.0 .
Odd even numbers are calculated separately and then merged.

Label control +1,-1 with flag.

#include Be careful to define its type, divide it into two parts, and define it as "I" to see if the denominator is an odd or even number, and the sum is summed. C language: Calculate 1/1-1/2+1/3-1/4+
Compile a function. When n is an even number, call the function to calculate 1/2 + 1/4 +... + 1/n. When n is an odd number, call the function 1/1 + 1/3 +... +
There are many formulas for calculating pi pai in history, in which Gregory and Leibniz found the following formula:
Pai = 4* (1-1/3+1/5-1/7 ...)
The formula is simple and graceful, but in a bad way, it converges too slowly.
If we rounded to keep its two decimal digits,

This is an interesting one. I just learned it when I went to school.C LanguageWhen I started my first lesson on data structure, the teacher gave me the following question:Use programming: 1/1! + 1/2! + 1/3! +... + 1/n!Then I thoug
Problem description: there are now n ordered arrays in M groups, such as {1, 2, 3, 4}, {2, 3, 6}, {1, 3, 5, 7 }, select the data smaller than K in these arrays and return this value.
Idea: Compare the minimum data selected each time by referring to the process of merging two
