This paper mainly describes how gcc generates static library (. a) and dynamic library (. so) to help us better carry out embedded programming. Because sometimes security is involved, static libraries or dynamic libraries may be provided for us to use. System environment: Ubuntu Desktop 18.04 1, What are static and dynamic libraries We u ...

C Language Programming All code shows the code inside the main function Computer thinking Rolling-Rotating Division int u = 32; int v = 32; //If v=0, at the end of the calculation, u is the greatest common divisor //v!=0 calculates the remainder of u/v so that u=v=the remainder while(v!+0) { int temp = u%v; u = v; v = temp; } print ...

1005 continue (3n+1) conjecture (25 points) Callatz conjecture has been described in 1001. In this subject, the situation is a little complicated. When we verify the karatz conjecture, in order to avoid repeated calculation, we can record every number encountered in the recursive process. For example, when verifying n=3, we need to calculate 3 ...

    speaking of printf() function, students who write code must be very familiar with it. This is a standard printing function in C language, which is often used when debugging code or information output. The conversion of printf function is described as follows: Conversion description modifier Tags in printf() The following ...

Program translation environment In any implementation of ANSI C, there are two different environments for program translation and execution. The first is the translation environment, in which the source code is converted into executable machine instructions. The second is the execution environment, which is used to actually execute cod ...

(1) . the size range of the number of customs clearance judgments by the computer: //The number shall not be greater than five digits; int x; int n=0; scanf ("%d",&x); if (9999>x>999){ n=4; }else if (999>x>99){ n=3; }else if (99>x> ...

Foreword: Why is there dynamic memory allocation? We already know how to open up memory as follows int a=10;//Open up 4 bytes on stack space char arr[10]={0};//Open up 10 bytes of continuous space on stack space The above method of opening up space has two drawbacks: 1. The size of space development is fixed. 2. Arrays must be declare ...
