I want to create a program that that will only accept one decimal point in a string (ex. 15.7) if the string has more than one decimal (ex. 5.5.2) I want to make isInteger false using a for loop with an if statement nested...

for(int index = 1; ....... ; index++)

{

decimalCount++

if(decimalCount > 1)

{

isInteger = false;

}

}

Basically want to find out if the number of decimal points is more than 1, if so integer is equal to false. Stuck on this simple problem, no matter what i do i cant get the program to see the decimal and identify the string as false. The rest of the program has exausted my mind ....This is a C++ program, if Im missing any info pls inform and request thx.
