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
Idea: If we were to fill 0 in front of the number , we would find that the N-bit all 10 binary number is actually N from 0 to 9 of the full array. That is to say, we arrange each digit of the number from 0 to 9, and we get all the 10 binary numbers. 1 /**2 *ch Storing numbers3 *n n Number of digits4 *index Count Value5
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 +... +

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
In the previous section, the flowchart we drew, remember? Judging the part we will, the difference cycle, below I will introduce three kinds of commonly used loops.Loop structure while loop (when looping, at least my C language teacher calls it)Let's introduce the syntax, as follows while (conditional expression) { // Here is the loop body, when the above condition expression is true, the loop body is executed, otherwise exits }While followed by a conditional expression, the loop is executed
