In C programming printf() is used for outputting a data or to display a data. On the other hand, scanf() is used to take input values from the users.
Input and Output of integer value.
#include
int main() {
int age;
printf("Enter Input value: ");
scanf("%d", &age);
printf("Age = %d", age);
return 0;
}
Why we use & with scanf()
It is because, & helps to point towards the memory location of that variable.
Input and Output of double and char values
int main() {
char alphabet;
double number;
printf("Enter a character: ");
scanf("%c", &alphabet);
printf("Enter a number: ");
scanf("n%lf", &number);
printf("alphabet is %c", alphabet);
printf("nnumber is %.2lf", number);
return 0;
}
Inputting 2 values together
#include
int main() {
char alphabet;
double number;
printf("Enter input values: ");
scanf("%lf %c", &number, &alphabet);
printf("alphabet is %c", alphabet);
printf("nnumber is %.2lf", number);
return 0;
}
