百度试题 结果1 题目function should return a value; 'void' return type assumed 这句C语言错误信息是什么意思?相关知识点: 试题来源: 解析 函数应该返回一个值,void返回类型被假定.反馈 收藏
在C语言编程中，函数应当返回一个值，但有时候我们可能会遇到“function should return a value; 'void' return type assumed”的警告。这种警告通常出现在函数声明与函数体实现不一致时。例如，如果一个函数声明为返回int类型，但在函数体中没有明确返回一个int值，编译器就会产生这样的警告。对于您提到...
1.改为空类型，即将main()改成void main()；2.不加void的话主函数默认返回值是int，所以可以把main()改成int main(),再在主函数末尾加入renturn （0）；3.直接只加入return（0）；还有就是这跟编译环境有关，有的环境要求不是很高，就不会报错，可能有警告，但不会影响运行。主函数没有返回值...
c语言编译错误function should return a value; 'void' return type assumed #include<stdio.h> main() { int i,j; for(i=1;i<=4;i++) { for(i=1;i<=4-j;i++) printf( ); for(i=1;I<=2*j-1;i++) printf( * ); printf( \n ); } } 到底那里错了?
languageC. I am working on an open source code base written inC. While working on one of its function, I wanted to be sure if I have correctly understood the return value of the following function. Can someone please help me understand what exactly belowfunctionbucket_straw2_chooseis ...
In inline TVFs, the TABLE return value is defined through a single SELECT statement. Inline functions don't have associated return variables. In MSTVFs, @return_variable is a TABLE variable, used to store and accumulate the rows that should be returned as the value of the function. @ retur...
从报错信息来看，问题出在main函数的返回值上。仅仅写下return语句时，编译器会假设返回类型为void，而int main的定义要求返回类型是int。因此，为了符合标准，应将return语句修改为return 0；在C语言编程中，main函数的返回值具有重要的意义。它不仅表明程序是否成功执行完毕，还可能返回给操作系统一些信息。
这个不是错误，而是一个警告。意思是说001.c这个源文件里的main()函数没有返回值。你这样写就不会出现这个警告了：int main(void){ printf("this is a C program.\");return 0;} 注意
return 0; } This code calls the cleanup function just before exiting the program. Best Practices and Consideration Note that the priorities are contradictory in the exist() function. These are not just thoughts. You should avoid exit() for reusable libraries. In a multithreaded program, exit()...
The range arguments must always be the same in SUMIFS. That means thecriteria_rangeandsum_rangearguments should refer to the same number of rows and columns. In the following example, the formula is supposed to return the sum of daily sales of Apples in Bellevue...
