ptr=malloc(sizeof(char)*4);
if length of available characters in string is more than 4 then memory allocation to pointer cross the limit but it does not affect the output to print the string.

It does not affect the output to print the string even if it goes/accesses out of the memory bounds allocated to it. But it may not get affected until that out of the bound memory is either not over-written by the process which owns it or it is still not allocated to any process by the operating system.
