Dada una string str , la tarea es verificar si el número de vocales en la string dada es primo o no. Si es primo, imprima SÍ; de lo contrario, imprima NO .
Ejemplos:
Entrada: str = “geeksforgeeks”
Salida: SÍ
El número de vocales es 5 (e, e, o, e y e) que es primo.Entrada: str = “aeioua”
Salida: NO
Enfoque: Inicialice una variable count = 0 y recorra la string carácter por carácter, si el carácter actual es una vocal, entonces actualice count = count + 1 . Al final, si el recuento es primo, imprima SÍ; de lo contrario, imprima NO .
A continuación se muestra la implementación del enfoque anterior:
C++
