Combining String Error

Using Arduino Programming Questions

Can someone help me with this error?

//Combine Strings

void setup() {
Serial.begin(9600);

String name = "Tom";
int age = 24;
int gradYear = 2008;
String college = "South Dakota State";
String degree = "biology";

String aboutMe = "Hello my name is " + name + " and I'm " + age + " years old.";

//ERROR: Invalid operands of types 'const char' and const char [14] to binary 'operator+'
** String education = "In " + gradYear + ", I attended " + college + " to pursue a degree in " + degree + ".";**

Serial.print(aboutMe);
Serial.println(education);
}

void loop() {

}

How do you propose to add a string and an int? Should the result be a long? Or maybe a float?

The + operator is addition.

See : WString.h

friend StringSumHelper & operator + (const StringSumHelper &lhs, int num);

The problem is probably a bug

This works :

String education = "In ";
education+=gradYear;
education+=", I attended " + college + " to pursue a degree in " + degree + ".";

and prints : "In 2008, I attended South Dakota State to pursue a degree in biology."

the first concatenation (aboutme) works fine and prints "Hello my name is Tom and I'm 24 years old."

Yeah, in OP's code. Not in the String class. None of the operands are Strings, so your assumption that plus means concatenate is wrong.
