How to store negative integer in c
WebThe syntax to declare a new variable in C++ is straightforward: we simply write the type followed by the variable name (i.e., its identifier). For example: 1 2 int a; float mynumber; These are two valid declarations of variables. The first one declares a variable of type int with the identifier a. WebTo assign negative numbers “signed” type qualifier is used. I believe most compilers use signed char by default. To retrieve the negative number assigned a simple printf statement with integer format specifier (%d) will suffice. Example : signed char a = -46; printf (“%d”,a); // prints: -46 printf (“%c”,a); // prints: π (did you know? :))
