The function isgreaterequal() is used to check that the first argument is greater than or equal to the second one. It is declared in “math.h” header file in C language. It returns true on success, otherwise false.
Here is the syntax of islessgreater() in C++ language,
bool isgreaterequal(value1 , value2);
Here,
value1 − This is the first argument which will be checked with value2.
value2 − This is the second argument which is used to check value1 that is greater or equal.
Here is an example of isgreaterequal() in C++ language,
Example
#include<iostream> #include<math.h> using namespace std; int main() { int val1 = 28; int val2 = 8; bool result; result = isgreaterequal(val1, val2); cout << "val1 isgreaterequal than val2 : " << result << endl; return 0; }
Output
val1 isgreaterequal than val2 : 1
In the above example, two values are compared and one of them is less or greater than the other. It checks value1>value2 || value1=value2. If one of them ( value1>value2 OR value1=value2 ) is true, it will return 1. Otherwise, it will return 0.
Now, let’s see another example when first value is less than second,
Example
#include<iostream> #include<math.h> using namespace std; int main() { int val1 = 5; int val2 = 8; bool result; result = isgreaterequal(val1, val2); cout << "val1 isgreaterequal than val2 : " << result << endl; return 0; }
Here is the output,
Output
val1 isgreaterequal than val2 : 0
