Renne Alinn Herrera 7.18.2007 Functions Functions: executes a certain task when indicated. Syntax: returntype Definitions Returnytpe: once the function executes, it returns the "type" of answer labeled. Another option can be `void' which does nothing in return. Examples: char, int, float etc.... Functionname: it is the name of the function assigned. Note: usually the name of the function relates to what it actually does or a meaningful name. Parameter list: designates the type of variable and the name given. Example: char wateva Function example #include <stdio.h> int add(int a, int b){ int result = a + b; result = a + b; return result; //or can write // return result; main(){ int int int } //all the program example does is there are variables assigned in the main program and when it reaches the `add' function the program will JUMP to the top num1 = 10; = num2 20; sum; note:result must receive appropriate "returntype" functionname(parameter list){ }
} void
sum = add(num1, num2);
NOTE: IF GOING TO COPY/PASTE CODE TRY TO USE A FUNCTION INSTEAD. CAN HAVE THE SAME VARIABLE NAME FOR DIFFERENT FUNCTIONS.
Function example #include <stdio.h> #include <math.h> float square(float num){ float answer = num * num; return answer; ) int add(int b){ int answer; a = 40; answer = a + b; return answer; } void main(){ int int int float num1 = 10; num2 = 20; sum; ans...
