To avoid overflows in general, try one of these techniques: Keep integer variable values restricted to within half the range of signed integers. In operations that might overflow, check for conditions that can lead to the overflow and implement wrap around or saturation behavior depending on how...
The C11 standard states that unsigned integer overflows result in wrap-around behavior. However, a wrap around behavior might not always be desirable. For instance, if the result of a computation is used as an array size and the computation overflows, the array size is much smaller than expe...

One way to address signed overflow is to use larger types. If you don’t need to represent negative numbers, another option is to use unsigned types, which wrap on arithmetic overflow. Alternatively, pass the-fwrapvflag to the compiler to enable signed wraparound on overflow. However, this ...

The behavior of both lines of code is undefined since integer overflow causes signed integer types to wrap around. In this case, the value INT_MAX + 1 wraps around to the smallest possible value of a signed integer, and adding 1 to INT_MAX also results in the same value, which ...

Although a number of tools for finding these bugs exist, the situation is complicated because not all overflows are bugs. Better ...
Simple question: Does anyone know if the standard specifies what happens when integers overflow? Through some experimentation with intel 11.1.046 it looks like the value of the integer seems to wrap around. i.e [fortran]PROGRAM int_explodeIMPLICIT NONEINTEGER :: my_intmy_int = HUGE(my_int)...

An integer overflow is a type of an arithmetic overflow error when the result of an integer operation does not fit within the allocated memory space. Instead of an error in the program, it usually causes the result to be unexpected.
