General syntax: Function definition(variable(s)) { variable declaration; condition1 base case; condition 2 recursive case; return(variable); }

Program of Factorial: ,[object Object],[object Object]

Using For loop: Int factorial (int n) { int f=1,i; for(i=n;i>=1;i--) f=f*i; return (f); }

Characteristics: ,[object Object],[object Object],[object Object]

Using recursion: Int rec(int n) { int f; if(n==1) return (1); else f=n*rec(n-1); return (f); }
