Similar things can be done for string values, and enumerations, as long as the default value can be converted to the given type. On a C++14 compiler, you can pass a callback function directly to .add_flag, while in C++11 mode you'll need to use .add_flag_function if you want a ...

main( ){ int i=1,s=0;while(i<=10) {s+=i;i+=2;}printf(“s=%d\n”,s);}这一程序的输出结果是___
Sets the designated paramter to the givenStringobject. The driver converts this to a SQLNCHARorNVARCHARorLONGNVARCHARvalue (depending on the argument's size relative to the driver's limits onNVARCHARvalues) when it sends it to the database. ...

我想说的是这是个半吊子程序，根本做不了什么事，也许是你没copy完。但是这是程序主要部分，至于sum必须初始化为0；可以写成这样for（int i=1，sum=0；i<=n;i++）sum+=i；至于后面的sum+=i就是sum=sum+i；然后循环就是了！！！这个就是优先级的问题（去看循环和优先级就明白了！！！）...

do……while，是先执行完DO后的语句才来判断WHILE中的条件，即I=7时才结束。continue其作用为结束本次循环，即跳出循环体中下面尚未执行的语句。此时I为偶数时不执行I++；S+=I：这两句。故最后的结果为16
