I know the output is 1236, 1234, 1239, 1231. Can someone explain the logic without programming the code? Thanks.

1) What is the program output? (VC++ running on on Windows PC) #include #include struct student char name[40] char phone_no[30]; char major_code[10] int id_no; int flag; float gpa int main(int argc, char** argv)1 struct student std[10] struct student "std2; std2 = std; std[0].gpa -3.0; std[0].idno = 1234; std[1].gpa -2.0; std[1].id no =1235; std[2].gpa -2.5; std[2].idno = 1 236; std[3].gpa 2.7; std[3].id_no-1237; std2->id-no = 1236; std2[1].idno = 1234; ("(std2+2)).id.no = 1239; ((std+3)).id_no 1231; printf("%din", std[0].id..no); printf("%din", std[1].id..no); printf("%dln", std[2].id-no): printt("%din", std[3].id..no); getchar); return 0
