警告，编译器的警告，说明程序没有错误，可以运行，但是有小问题。当然很可能这个小问题会导致运行结果完全和想象的不一样。你这个应该就是了。n和p没有被初始化。虽然程序照样可以运行，但是n和p的值，估计不是你想要的inta,b,c;floatd,e,f;longg,h,i;cin>>a>>b>>c;cin>>d>>e>>f;cin...
题目local variable 'l' used without having been initialized#include <stdio.h> void main() { int max(int x,int y,int z); int a,b,c,e; scanf("%d,%d,%d",&a,&b,&c); e=max(a,b,c); printf("max=%d\n",e); } int max(int x,int y,int z) { int l; if(x>y,x>z) ...
其实就有一个错误，简单的不行。这条语句有问题，scanf("%lf%c%lf,&a,&c,&b");改成：scanf("%lf%c%lf",&a,&c,&b);好了。

针对你提出的问题“local variable 'c' used without having been initialized”,我们可以按照以下步骤进行分析和解决: 确认变量'c'的作用域: 首先,需要确认变量c是在哪个作用域内定义的。如果c是在函数内部定义的局部变量,那么它只在该函数内部有效。 例如: c void exampleFunction() { int c; // c的作用域...
C. Declaring a variable of type table The following example creates atablevariable that stores the values specified in the OUTPUT clause of the UPDATE statement. TwoSELECTstatements follow that return the values in@MyTableVarand the results of the update operation in theEmployeetable. The results...
Static local variables are used when you need a local variable to remember its value across function calls. Best practice Initialize your static local variables. Static local variables are only initialized the first time the code is executed, not on subsequent calls. Tip Just like we use “...
J. Print the value of a variable initialized by using SET The following example creates the@myVarvariable, puts a string value into the variable, and prints the value of the@myVarvariable. SQL DECLARE@myVarCHAR(20);SET@myVar ='This is a test';SELECTTOP1@myVarFROMsys.databases; ...
The var keyword in C# instructs the compiler to infer the type of the variable from the expression on the right side of the initialization statement.
