here translation:

program has stopped working

a problem caused program work correctly. windows close program , notify if solution available.

here source code:

i appreciate how fix error.

the comments true. should learn use loops.

having said that, issue more using uninitialized variables. see this:

u78=i678*r78 

the value of i678 uninitialized, you're using compute u78. visual studio reports these variables being used before initialization:

1>warning c4700: uninitialized local variable 'r78' used 1>warning c4700: uninitialized local variable 'u12345' used 1>warning c4700: uninitialized local variable 'u123' used 1>warning c4700: uninitialized local variable 'i2' used 1>warning c4700: uninitialized local variable 'u4' used 1>warning c4700: uninitialized local variable 'r4' used 1>warning c4700: uninitialized local variable 'i9' used 1>warning c4700: uninitialized local variable 'r9' used

you're using these directly or indirectly in lines division, if uninitialized, program exhibit undefined behavior. initialize variables, format code better line isn't umpteen characters in length, , start use loops.
