1．编程：从键盘输入一个英文字母，判断大小写，若是大写，输出“uppercase”，否则输出“lowercase”。部分程序如下： #include intmain(void) { charch; ch=getchar(); if() printf("uppercase%c\n",ch); else printf("lowercase%c\n",ch); return0; }

函数$f(x)=x+\sin x$的( )。 A: 上凸区间为$(2n\text{ }\!\!\pi\!\!\text{ },(2n+1)\text{ }\!\!\pi\!\!\text{ })$,下凸区间为$((2n-1)\text{ }\!\!\pi\!\!\text{ },2n\text{ }\!\!\pi\!\!\text{ })$ B: 上凸区间为$((2n-1)\text{ }\!\!\pi\!\!\text{ },2n\text{ }\!\!\pi\!\!\text{ })$,下凸区间为$(2n\text{ }\!\!\pi\!\!\text{ },(2n+1)\text{ }\!\!\pi\!\!\text{ })$ C: 上凸区间为$(n\text{ }\!\!\pi\!\!\text{ },(n+1)\text{ }\!\!\pi\!\!\text{ })$,下凸区间为$((n-1)\text{ }\!\!\pi\!\!\text{ },n\text{ }\!\!\pi\!\!\text{ })$ D: 上凸区间为$((n-1)\text{ }\!\!\pi\!\!\text{ },n\text{ }\!\!\pi\!\!\text{ })$,下凸区间为$(n\text{ }\!\!\pi\!\!\text{ },(n+1)\text{ }\!\!\pi\!\!\text{ })$
