Task $2$: Run the following code ready for string functions. Use one function at a time and observe the output$\mathrm{.}2\mathrm{.}1$ What is the purpose of the strcpy$()$ function in this code?$2\mathrm{.}2$ What would be the result if we uncommented the line $//$strcpy$($b$,$a$)$;$?$ Explain$\mathrm{.}2\mathrm{.}3$ If we uncommented the line $//$strncpy$($a$,$ b$,2)$;$,$ what would be the value of string a after executing that line?$2\mathrm{.}4$ Describe the functionality of the strcat$()$ function. What would be the result if we uncommented the line $////$strcat$($a$,$b$)$; $?2\mathrm{.}5$ Explain what happens when we use the strncat$()$ function. If we uncommented the line $//$strncat$($a$,$b$,3)$; $,$ what would be the value of string a after executing that line?$2\mathrm{.}6$ What is the purpose of the strlen$()$ function? What would be the value of x if we uncommented the line $////$x$=$strlen$($a$)$;$?$
