Answer :

Garbage values.

Explanation:

Both the functions suffer from the problem of dangling
pointers. In someFun1() temp is a character array and so the
space for it is allocated in heap and is initialized with
character string “string”. This is created dynamically as
the function is called, so is also deleted dynamically on
exiting the function so the string data is not available in
the calling function main() leading to print some garbage
values. The function someFun2() also suffers from the same
problem but the problem can be easily identified in this case.

Answer / rahulkulkarni

Variables are in function calls, hence on heap space. Variable address is being returned by function and when function returns the allocated space is freed.

Now accessing returned address will result in : segmentation fault.

As address no longer allocated to function, results in invalid address accessed by process.
As variable address does not exist ( hence variable address also , as heap is freed).

Under linux environment can u please provide a c code for computing sum of series 1-2+3-4+5......n terms and -1+2-3+4-5...n terms..

Write a C program to print look and say sequence? For example if u get the input as 1 then the sequence is 11 21 1211 111221 312211 12112221 .......(it counts the no. of 1s,2s etc which is in successive order) and this sequence is used in run-length encoding.
