  • int* i; or int *i; or int * i; - i; - Software Engineering Stack Exchange
    I prefer int* i because i has the type "pointer to an int", and I feel this makes it uniform with the type system Of course, the well-known behavior comes in, when trying to define multiple pointers on one line (namely, the asterisk need to be put before each variable name to declare a pointer), but I simply don't declare pointers this way
  • int * vs int [N] vs int (*) [N] in functions parameters. Which one do . . .
    In practice, you'll see int accumulate( int n, int *array) most often It's the most flexible (it can handle arrays of different sizes) and most closely reflects what's happening under the hood You won't see int accumulate( int (*array)[N] ) as often, since it assumes a specific array size (the size must be specified) If your compiler supports variable-length array syntax, you could do int
  • history - Why is int in C in practice at least a 32 bit type today . . .
    Why is int in C in practice at least a 32 bit type today, despite it being developed on for the PDP-11, a 16 bit machine?
  • Why should C++ uint8_t data not be printable?
    On this github C++ related page the writer said Note that the value_type of those two containers is uint8_t which is not a printable character, make sure to cast it to int before you print Why s
  • size_t or int for dimensions, index, etc - Software Engineering Stack . . .
    It is valid for the compiler to typedef size_t to be unsigned int, and it's also valid for it to be typedefed to unsigned long If you use int or long directly, you'll eventually run into compilers where a person who thinks your class followed the STL's style gets trapped because you didn't follow the standard
  • Why are variables declared without a value in C?
    So modern coders see int v2=0; as a simple declaration and don't assume the 0 means anything other than "make the compiler happy", but in old C it stuck out as "I intentionally want this to start at 0" Back then you wouldn't write that unless you meant it (*) at some times, at some places, by some people, was considered good style
  • What does the t in int32_t signify? - Software Engineering Stack Exchange
    In C, what meaning, if any does the t at the end of integer types like uint8_t and int32_t have? Where did it originate? Why wasn't the type just called int32?
  • How does long long syntax work when int int doesnt in C++?
    I was wondering if long long specifies a single datatype then why don't things like int int work? I meant obviously that's not a data type but there is a long data type
  • Why are there so many numeric types (bit, int, float, double, long)?
    Typical examples in C would be int, float, and unsigned int, respectively Fixed-point types are a subcategory of discrete types, but algebraic rings are fundamentally different from numbers [must of the confusion regarding unsigned types in C stems from the fact that they mostly behave like rings rather than numbers, but aren't quite consistent]
  • programming practices - Should I avoid using unsigned int in C# . . .
    Also there might be some cases where an unsigned int may actually inadvertently produce more errors (though probably ones immediately spotted, but a bit confusing) -- imagine looping in reverse with an unsigned int counter because some size is an integer: for (uint j=some_size-1; j >= 0; --j) -- whoops (not sure if this is an issue in C#)!
