please make sure to follow all instructions listed , this is to be done in Ubuntu / Virual box using c programming .

please make sure to include comments throughout code for a better understanding

thank you in advance !

you may use code similar to this , or refer to this as an example for help

please and thank you

Part A Create a single threaded application that forms the sum save this as prog_parta.c. Note: N can be a very large number so make the variable of long long type. The result is to be stored in a global long long variable. Use as a format specifier Mild Part 3 Modify prog_parta.c to be a threaded version where the main() spawns a single thread. Save as prog_partb.c Note the result of this computation Part Modity prog_partb.c have a variable offset. That is instead of $$\sum _{i1}N 15$ form offseri param. Here N can be a a global variable as well. Test with offset_param=1. Compare to Part B. #define N 4002394023945803948 Part D Modify pro partec to have two threads using the same summing function. The first thread should use an offset parameter as 1 and the second should use an offset parameter 1. What is the theoretical result? What is the actual result? HINT: You could do something like the following int offset11 Int offset2n-offsett: Deliverables A zipped file containing all of the programs and a text file with the requisite commentary. #include #include #include int sum, sum2; struct more_info { char *first_parameter; char * second parameter; void *runnerl (void *param); void * runner2(void *param); void *print Param(void *param); int main(int argc, char *argv[]) { pthread_t tidi, tid2, tid3; pthread_attr_t attr; struct more info myinfo; if(argc != 3) { printf ("Usage : threadit "); return -1; } if(atoi (argv[1]) first_parameter); sum1 0; for (i=0; isecond_parameter); sum2 = 0; for (i=0; ifirst_parameter); sumi 0; for (i=0; isecond_parameter); sum2 = 0; for (i=0; ifirst parameter); printf("Second parameter %s ", arg->second parameter): Part A Create a single threaded application that forms the sum save this as prog_parta.c.
