Exercise 1E:
A C program contains the following statements:
#include <stdio.h>
Int I,j,k;
Write an appropriate scanf function to enter numerical values for I,j and k, assuming
(a) The values for I,j and k will be decimal integers.
7
#include<stdio.h>
main()
{ int i,j,k; printf("Insert value of i:\n"); scanf("%d",&i); printf("Insert value of j:\n"); scanf("%d",&j); printf("Insert value of k:\n"); scanf("%d",&k); return 0;
}
(b) The values I will be decimal integer, j an octal integer and k a hexadecimal integer.
8
#include<stdio.h>main(){ int i,j,k; printf("Insert value of i:\n"); scanf("%d",&i); printf("Insert value of j:\n"); scanf("%f",&j); printf("Insert value of k:\n"); scanf("%f",&k); return 0;}
(c) The values for I and j will be hexadecimal integers and k will be an octal integer.
9
#include<stdio.h>main(){ int i,j,k; printf("Insert value of i:\n"); scanf("%f",&i); printf("Insert value of j:\n"); scanf("%f",&j); printf("Insert value of k:\n"); scanf("%f",&k); return 0;}
