A number of things are jumping out at me about your code. You are allocating memory for num<\/code> integers, when num<\/code> is uninitialized. It is given an undefined trash value. See undefined behavior<\/a>. You must put your scanf statement before your malloc, because as it stands right now your code does not make sense. <\/p>\n

for ( i=0;i<num;i++)\n{\n    scanf(\"%llu\",&num_alloc[num]);\n    FinalSum =FinalSum + num_alloc[num];\n}\n<\/code><\/pre>\n
For each loop iteration, you are accessing the num<\/code>th element of your array. This is not possible as num_alloc<\/code> should be an array of num<\/code> ints, and array indexes in C start at 0. But what I’m pretty sure what you meant to do is this. With your code, you would have been assigning the same value over and over again.<\/p>\n
for (i = 0; i < num; i++) {\n    scanf(\"%llu\", &num_alloc[i]);\n    FinalSum += num_alloc[i];\n}\n<\/code><\/pre>\n
You must also free()<\/code> any memory you allocate on the heap with malloc()<\/code>.<\/p>\n
free(num_alloc);\n<\/code><\/pre>\n<\/p><\/div>\n
