C++ Algorithm Function find_if()
C++ Algorithm find_if() function returns the value of the first element in the range for which the pred value is true otherwise the last element of the range is given.
first: It specifies the first element of the range.
last: It specifies the last element of the range.
pred: It is usually a unary function for which the range values are checked to return a boolean answer.
The function returns an iterator to the first element of the range for which the pred value is true. If no such element is found, then the function returns the last element.
Out of the given elements, first odd element is 35
Out of the given elements, first odd element is 20
The function moves in a linear way, starting from the first element going towards the last one. For each element of the list value of 'pred' is checked. The search goes on until a mismatch for the 'pred' value is encountered.
Either all the objects in the specified range or some of them are accessed by the function.
The function throws an exception if any of the argument throws one.
