for loop incrementing
-
can a FOr loop be incremented twice at a time? such as for(i=1; i<=100;i+2).. as i need to have only odd numbers. Is it correct?

should be :
for(int i=1; i<100; i+=2){}Regards, Nish

Hello chaitanya
for(inintializer;condition;incrementer)Here in place of incrementer you can put any statement regards of assigment statement. It is not require that you use only a variable that is use in initializer place. C design a very richforloop as you never seen before.

You can even have multiple items in your loop, such as: for (int i = 2, j = 3; i < 5 && j < 10; i++, j+=3) da Big_R

If you do not want to make your for loop look anything other than the ordinary, but still want to skip processing the evens, use the continue keyword...
for( i = 1; i <= 100; i++ ) { if( i % 2 == 0 ) continue; //.... }Koushik Biswas -

or...
int b=0,c=0,q=60,_=q;for(float i=-20,o,O=0,l=0,j,p;j=O*O,p=l*l,
(!_--|(j+p>4)?fputc(b?q+(_/3):10,(i+=!b,p=j=O=l=0,c++,stdout)),
_=q:l=2*O*l+i/20,O=j-p+o),b=c%q,c<2400;o=-2+b*.05); -

for( i = 1; i <= 100; i++ ) { if( i % 2 == 0 ) continue; //.... }Koushik BiswasWhile this code works, it might not be as intuitive, and more importantly, efficient as:
for (int i = 0; i < 100; i += 2) { // do something }Might not be important for small loops, but an extra if and % op can add up in big loops. - delete that; -
