The norm is for strings to be null-terminated. &nbsp;If so:<br />
<br />
unsigned int x = strlen(str);

<div class="content wysiwyg-content">
void main()<br />
{<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;char str[2000];<br />

Other way could be<br />
void main()<br />
{<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; char *str=(char*)malloc(sizeof(<wbr />char)*(no.<wbr />of characters));<br />
}<br />
How can i get the no. of characters in c at runtime.<br />
<br />
Is there any way to input a string dynamically without fixing the size.

How to read a string in c dynamically,

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
