&lt;p&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; C language has evolved from three different structured language ALGOL, BCPL(Basic combined programming language) and B Language(B language is developed by Ken Thompson in 1970).&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; C is also called an offspring of the BCPL.&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; BCPL and B are data type less language. However, C language has a variety of data types.&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; It uses many concepts from these languages and introduced many new concepts such as data types, struct , pointer.&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; In 1989, the C language was standardizes by American National Standard Institute(ANSI).&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; In 1990, a version of C language was approved by the International Standard Organisation(ISO) and that version of C is also referred to as C89.&lt;/p&gt;
