对若干个正数求和，输入“ok”结束，下面正确的代码是（ ）。知识点：while循环。
A: s = 0x = input()while x!="ok": s += int(x) print(s)
B: s = 0while True: x = input() if x=="ok": break s += int(x) print(s)
C: s = 0x = input()while x!="ok": s += int(x) x = input()print(s)
D: s = 0while x!="ok": x = input() s += int(x) print(s)
A: s = 0x = input()while x!="ok": s += int(x) print(s)
B: s = 0while True: x = input() if x=="ok": break s += int(x) print(s)
C: s = 0x = input()while x!="ok": s += int(x) x = input()print(s)
D: s = 0while x!="ok": x = input() s += int(x) print(s)
举一反三
- 对若干个正数求和，输入“ok”结束，下面正确的代码是（ ）。知识点：while循环。 A: s = 0x = input()while x!="ok": s += int(x) print(s) B: s = 0while True: x = input() if x=="ok": break s += int(x) print(s) C: s = 0x = input()while x!="ok": s += int(x) x = input()print(s) D: s = 0while x!="ok": x = input() s += int(x) print(s)
- 输入若干个数字，直到输入-1为止，求输入的数字的和值并输出。 输入：1 3 4 8 -1 输出：16 程序代码如下，下划线处的代码应该是：( )。 s=0 x=eval(input()) while x!=-1: ___________________ print(s) A: x=eval(input());s=s+x B: x=eval(input());s=x C: s=x;x=eval(input()) D: s=s+x;x=eval(input())
- 下列程序段可以正确运行的有： A: int i,s,x;s=0;i=0;while（1）{ scanf("%d",&x); if(x!=-1) { s=s+x; i++; } else break;}printf("ave=%d\n",s/i); B: int i,s,x;s=0;i=0;scanf("%d",&x);while（x!=-1）{ s=s+x; i++; scanf("%d",&x);}printf("ave=%d\n",s/i); C: int i,s,x;s=0;i=0;while（1）{ scanf("%d",&x); if(x==-1) break; s=s+x; i++; }printf("ave=%d\n",s/i);
- x=input("x=")x=2*float(x)print(x)输入x=23b输出结果是 A: 46 B: 0 C: 错误 D: 4
- 对下面程序段描述正确的是 ______. int x=0,s=0; while (!x!=0) s+=++x; printf("%d",s);
