Day2 of my diary of C program learning

some bug I meet

1. if(a>b,a<c) should be if(a>b&&a<c)

2. scanf  forget'&''

3. exp1?exp2:exp3 instead of exp1?exp2;exp3。while  for(;;)

4. As for exp1?exp2:exp3。exp==min=a,max=b 0;exp==(min=a,max=b) 1;

两个代码的区别

#include<stdio.h>

The first

intmain()

{

inti = 1, j = 1;

for(i = 1; i <= 6; i++)

{

for(j = 1; j < 7; j++)

printf("%d", j);

}

return0;

}

Output:123456123456123456123456123456123456

The second

intmain()

{

inti = 1, j = 1;

for(; i <= 6; i++)

{

for(; j < 7; j++)

printf("%d", j);

}

return0;

}

Outpput:123456
