Answer 1

Use this fgets(str, sizeof(str), stdin); instead of gets(str)

and line 23 is Wrong. here should be str[i] == ' ' but you have str[i] = ' ';

= it's mean assignment and == it's mean equality

Answer 2

Purushotham this error is because gets() function is not a standard function anymore because it can crash your code by overflowing your buffer.
