Hi All,

When we define the constant size of string, then it should take input of that particlur size but

it does not do so.
For example:-

char str[5];

The above string should take input of maximum size 5, but it can take input of any size greater

that 5.
Why it is so....???

Thanx:

Don't forget that when the size of a char string is declared, one of the spaces in memory is used for the null terminator (/0) at the end of the string. So, in you example, str would hold 4 characters.

The above string should take input of maximum size 5, but it can take input of any size greater

it will compile and maybe sometime work but it a very bad idear. when you declear char a[5] you are reserving space for 5 chars in memory. when you go over that space you are over riding memory space not reserve for it. this can have extremly un expected results.
