How to convert string to hex value in C -

i have string "6a" how can convert hex value 6a? please me solution in c i tried char c[2]="6a" char *p; int x = atoi(c);//atoi deprecated int y = strtod(c,&p);//returns first digit,rest considers string , //returns 0 if first character non digit char. the question "how can convert string hex value?" is asked, it's not quite right question. better "how can convert hex string integer value?" the reason is, integer (or char or long) value stored in binary fashion in computer. "6a" = 01101010 it in human representation (in character string) value expressed in 1 notation or another "01101010b" binary "0x6a" hexadecimal "106" decimal "'j'" character all represent same value in different ways. but in answer question, how convert hex string int char hex[] = "6a"; // here hex string...

doctrine - DDD PHP Doctrine2 - Mapping -

i hear how peoploe map domain objects data mapper pattern in doctrine2. went problem, when aggregates use clean php array , use php functions work array array_shift example. anyway till started integrate doctrine mappings domain entities. problem how doctrine works assosciations between entities. whenever aggregate root had 1 many relationship (or other tbh), doctrine used arraycollection class on that, instead of normal array. use 1 of methods toarray(), have check first in domain object if doctrine collections class, dirty. anyway chose in aggregate repository, before returning class. made reflection class set property public , replaced clean php array. works less dirty, still dont tbh. question is, how guys handle limitations od doctrine or maybe there no limitation :). , next question, if guys use doctrine arraycollection in domain classes? what using array for? i suspect problem using arrays instead of objects. objects should reflect domain , provide methods exi...

C++ template return types -

i have 2 template classes, vector3 , matrix4x4. vector3 explicitly instantiated float , double , int , whereas matrix4x4 explicitly instantiated float , double . i'm thinking return type user expect when multiplying them different types. internal multiplication happen such non-matching types promote 1 other, i'm not sure type return e.g. vector3i vec3i(1, 2, 3); matrix4x4f mat4f; //automatically set identity auto result = vec3i * mat4f; auto result2 = mat4f * vec3i; in both cases think result , result2 should both vec3f, if multiply int float . guess i'm wondering if in line common practice, or if not if, instead of multiplying different types, should doing explicitly casting 1 other static_cast , casting operators ?
