I have a variable which stores the date in string format
example.. lets say char a='2-12-2016'
i want to convert the format to 2016/12/2
How to achieve this using C?
a char stores a single character, so char a='2-12-2016' isn't going to work. For your question, check into strchr.
char s = "2-12-2016", *p;
while((p = strchr(s, '-')) != NULL)
*p = '//';
don't forget to include string.h for strchr
