[spy1120]

设计猜数字游戏：
首先让电脑产生一个〔1，100〕的随机数A，然后由用户猜测该数字A。如猜测的数字B大于A，则显示“High”，小于则显示“Low”，等于则显示“You Won”，同时退出游戏。用户最多可以猜7次。
程序：

%Play the game of guess the number
x=fix(100*rand); %a random number calculated by the computer
n=7;
test=1;
for k=1:7
numb=int2str(n);
disp(['You have a right to ',numb,' guesses'])
disp(['A guess is a number between 0 and 100'])
guess=input('Enter your guess:');
if guess<x
disp('Low')
elseif guess>x
disp('High')
else
disp('You won')
test=0;
break;
end
n=n-1;
end
if test==1
disp('You lost')
end
