Is it possible to set values for default parameters in C? For example:
void display(int a, int b=10){ //do something } main(){ display(1); display(1,2); // override default value } Visual Studio 2008, complaints that there is a syntax error in -void display(int a, int b=10). If this is not legal in C, whats the alternative? Please let me know. Thanks.

Default parameter in Javascript The default parameter is a way to set default values for function parameters a value is no passed in (ie. it is undefined ). In a function, Ii a parameter is not provided, then its value becomes undefined . In this case, the default value that we specify is applied by the compiler.
Default function parameters allow named parameters to be initialized with default values if no value or undefined is passed.
By default, C uses call by value to pass arguments.
Parameters and Arguments Information can be passed to functions as a parameter. Parameters act as variables inside the function. Parameters are specified after the function name, inside the parentheses.
Default parameters is a C++ feature.
C has no default parameters.

It is not possible in standard C. One alternative is to encode the parameters into the function name, like e.g.
void display(int a){ display_with_b(a, 10); } void display_with_b(int a, int b){ //do something } If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
