while(i++<n)
{
j=2*i;
sum=sum+i*2;
}
getch();
return 0;
}

ii). using do-while loop

int main()
{
int sum=0,n,i=0,j=2;
printf("Enter 2+4+6+...n upto nth term:");
scanf("%d",&n);

do 
{
j=2*i;
sum=sum+i*2;

Answer / srujitha

// while loop
int main()
{
int n = 3,sum = 0,i = 2, count = 0;

while(n > count)
{
sum = sum + i;
i = i+2;
count++;
}
printf("SUM = %d ",sum);
}

// do while loop

int main()
{
int n = 3,sum = 0,i = 2, count = 0;


do
{
sum = sum + i;
i = i+2;
count++;
}
while(n > count);
printf("SUM = %d ",sum);
}

Write an implementation of “float stringToFloat(char *str).” The code should be simple, and not require more than the basic operators (if, for, math operators, etc.). • Assumptions • Don’t worry about overflow or underflow • Stop at the 1st invalid character and return the number you have converted till then, if the 1st character is invalid return 0 • Don’t worry about exponential (e.g. 1e10), instead you should treat ‘e’ as an invalid character • Write it like real code, e.g. do error checking • Go though the string only once • Examples • “1.23” should return 1.23 • “1a” should return 1 • “a”should return 0
