Loop structure, commonly used for loops and while loops.For Loop 1 to 100 and:# include int main (void) {int I;int sum = 0;for (i=1;iOperation Result:Ask for an even number of 1 to 100 and a step of 2, i.e. i+=2# include int main (void) {int I;int

This involves a problem with the storage of floating-point numbers in the computer. You can test the following programs:# include int main (void) {Float i = 4.3123999;if (i-4.3123999==0) printf ("I is zero. \ n "); elseprintf (" I is not zero. ") \

here is static local variable, not with the end of the function to undo, placed in the main function is meaningless, the following is the example of static :void F (){static int x=0;int y=0;x + +;y++;printf ("%d%d\n", x, y);}void Main (){f ();f ();f
