exponentiation - Store and work with Big numbers in C -


i need working big numbers. according windows calc, exponent 

174^55 = 1.6990597648061509725749329578093e+123

how store using c (c99 standard)?

int main(){   long long int x = 174^55; //result 153   printf("%lld\n", x); }

normal types in c can store 64 bits, you'll have store big numbers in array, example, , write mathematical operations yourself. shouldn't reinvent wheel here - try gnu multiple precision arithmetic library purpose.

and comments pointed out, ^ operation binary xor. exponentiation, have use mathematical functions pow.

how to proxy from https to http with lighttpd -

i have internal site (192.168.2.1) accessible http on different server run public web-server using lighttpd. can make internal site accessible outside work follows $http["host"] == "internal.example.com" { ... proxy.server = ( "" => ( "internal" => ( "host" => "192.168.2.1", "port" => 8000 ) ) } this works, use https outside world. question is, how can proxy going https http ? i've tried this: $server["socket"] == ":443" { $http["host"] == "internal.example.com" { ... proxy.server = ( "" => ( "internal" => ( "host" => "http://192.168.2.1", "port" => 8000 ) ) } } but doesn't seem wor...
