Question!

.Use make -f Makefile to compile the three problem C programs Within Problem1.c we will use gdb ions . Within Problem2.c we will use assert then turn off . Within Problem3.c we will use gdb again and I will begin but you will need to finish . Assignment: run gdb and file Problem3.o ve odisplay val.cnt, out, tot (variables) o Set breakpoints on main and the line that throws the segmentation fault o Show the screenshot of the gdbsession when it receives the signal o (1)what is the problem? (2)What is the signal received (3)how could you fix this code?

Problem 1.c

Problem 2.c

Problem 3.c

Answer 1

hi, please go threw output and code.

solution.

#include <stdio.h>

int main()

{

int out =0, tot = 0, cnt = 0;

int val[] = {5,54,76,91,35,27,45,15,99,0};

while(cnt < 10)

{

out = val[cnt];

if(out > 0) // put here condition so that it will not became devide by 0

tot = tot + 0xffffffff/out;

cnt++;

}

printf("\n Total = [%d]\n",tot);

return 0;

}

- problem is at line 9 : tot = tot + 0xffffffff/out; and at line 5.int val[] = {5,54,76,91,35,27,45,15,99,0};

last elemenet of val is 0. so when out is geting 0 then it became devide by zero.

so it will give segmentation fault and will recive signal.

- signal is SIGFPE, Arithmetic exception.

- we can fix by putting if condition before deviding.we make sure it should be positive value.
