How to write for a loop?

[cool17]

printf("\nEnter the number of terms:\n");
scanf("%i",&j);
printf("\nPlease enter expression info as follow:\n");

{
double value;
double power;
double times;
int pos;
int isX;
int KnowX;


printf("-------- expression info:--------\n");
printf("What is the single value? =");
scanf("%f",&value);

printf("How many numbers of xtimes? =");
scanf("%f",&power);

printf("What is the power value? =");
scanf("%f",&times);

printf("What is the sign ? =");
scanf("%i\n",&pos);

}

with the above code how do i add the loop?Thank guys for the help

scanf("%f",&power);

printf("What is the power value? =");
scanf("%f",&times);

printf("What is the sign ? =");
scanf("%i\n",&pos);
function(); // that will be calculate the power
printf("if you want to calculate another one type 'e' otherwise program will close");

while(getche()=='e' );
}
return 0;

i add do while loop to your code
getche() function takes a character that will ask users request if user types e it loops again otherwise program will end...
i hope it was helpfull

thank for the help. But on the above of my code i ask user for the number of terms needed , i will den prodced the data as required... So is there any other ways of writting it?

for loops - general form


for( 'StartingCondition'; 'ConditionConstraint'; 'AdvanceCondition)
{

// Do stuff while ConditionConstraint is not met

}

Usually you write them in a form similar to below

int i;
for( i = startingvalue; i < maxvalue; i++)
{
cout << i << endl;
}

This states that I want to print all the integers from startingvale to maxvalue-1 because each time I run the loop, I increase i by 1 (i++).
