facing a problem while running my c++ program (run time error)

[Hala Civil]

good evening,well i'm kinda facing a problem while running my c++ program (run time error!!),the program contains a large number of if statements but all gathering around the same point,,,it's designed to assign values for factors z1f_a1 ,z2f_a1 ,z1r1_a1 , z2r2_a1, if certain conditions of H,A,K1,K2 are met...
the code is attached as a txt file,plz i need help before 40 hours.
thx :)

ok there's no syntax,but if you try those values:
q=120
E1=400000
E2=20000
E3=10000
h1=6
h2=6
a=4.8
then when the program asks you to enter 0 ir 1 press 1,then the program will stop ,giving a runtime error :(
