编码的奥秘
c语言:一个常量与一个变量相加:i =i+5;
在C语言中,可以简写为: i+=5;
如果只需要把变量加1(即增量),简写语句:i++;
1, 布尔数组从2-10000的所以数字来算法:
begin
Boolean array a[2:10000];
integer i, j
for i :=2 step 1 until 10000 do
a[i] := true;
for i :=2 step 1 until 100 do
if a[i] then
for j :=2 step1 until 10000 ÷ i do
a [i × j] :=false;
for i :=2 step1 until 10000 do
if a[i] then
print (i);
end
2,从1-100所以数的平方根
begin
real array a[1:100];
integer i;
for i :=1 step1 until 100 do
a[i] :=sqrt(i);
for i :=1 step 1 until 100 do
print ('The square root of', i,' is', a[i]);
end
