Change Variable Values
changing variable values involves altering the data stored within a variable after it has been declared and initialized. There are various ways to achieve this, depending on the context and scope of the variable:
Example
#include
int main() {
int myNum = 15; // myNum is 15
myNum = 10; // Now myNum is 10
printf("%d", myNum);
return 0;
}
Output
10
You can also assign the value of one variable to another:
Example
#include
int main() {
int myNum = 15;
int myOtherNum = 23;
// Assign the value of myOtherNum (23) to myNum
myNum = myOtherNum;
// myNum is now 23, instead of 15
printf("%d", myNum);
return 0;
}
Output
23
Add Variables Together
Adding variables together is a fundamental operation in many programming languages, and the + operator is most commonly used for this purpose. get example:
