I'm learning C language and stuck with a question as follows: #include<stdio.h> #include<conio.h> void main() { short int a=5; clrscr(); printf("%d"+1,a ...
Output: arr = geeks, sizeof(arr) = 17 str = geeks, sizeof(str) = 4. Let us first talk about first output "arr = geeks".When %s is used to print a string, printf starts from the first character at given address and keeps printing characters until it sees a string termination character, so we get "arr = geeks" as there is a \0 after geeks in arr[].
正是因为printf输出时表达式值的计算顺序是从右到左，先计算a=1，改变了a的值，a+2和a并没有改变a的值，不用计算。有了从右往左的思想后，我们引入栈这个内容，简单来讲就是一个死胡同，先进去的最后才能出来，最后进去的最先出来，在这里就是最后面的最先进入栈，最后打印。
Why int main()? As we discussed earlier, the main function is the starting point of program execution. Operating system (OS) initiates the program execution by invoking the main function. And it will expect an integer value from the main function. That integer value represents the status of the program.

Both the stack and heap memory segments during execution. Here's a breakdown: Stack: Function arguments (argc, argv): These arguments are passed to the main function and stored on the stack. Local variables: Variables declared within the main function, including input, ch, lCnt, and bCnt, reside on the stack. Return address: When the main function calls a function like fopen or printf, the ...
