Basic Data Types C++
Problem Statement :
Some C++ data types, their format specifiers, and their most common bit widths are as follows: Int ("%d"): 32 Bit integer Long ("%ld"): 64 bit integer Char ("%c"): Character type Float ("%f"): 32 bit real value Double ("%lf"): 64 bit real value Reading To read a data type, use the following syntax: scanf("`format_specifier`", &val) For example, to read a character followed by a double: char ch; double d; scanf("%c %lf", &ch, &d); For the moment, we can ignore the spacing between format specifiers. Printing To print a data type, use the following syntax: printf("`format_specifier`", val) For example, to print a character followed by a double: char ch = 'd'; double d = 234.432; printf("%c %lf", ch, d); Note: You can also use cin and cout instead of scanf and printf; however, if you are taking a million numbers as input and printing a million lines, it is faster to use scanf and printf. Input Format Input consists of the following space-separated values: int, long, char, float, and double, respectively. Output Format Print each element on a new line in the same order it was received as input. Note that the floating point value should be correct up to 3 decimal places and the double to 9 decimal places.
Solution :
Solution in C :
#include <iostream>
#include <cstdio>
using namespace std;
int main() {
// Complete the code.
int a,c;
long long b;
char d;
float f;
double e;
scanf("%d %d %lld %c %f %lf", &a ,&c,&b,&d,&f,&e);
printf("%0d\n",a);
printf("%0d\n",c);
printf("%0lld\n",b);
printf("%0c\n", d);
printf("%0f\n", f);
printf("%0lf\n", e);
return 0;
}

Pair Sums
Given an array, we define its value to be the value obtained by following these instructions: Write down all pairs of numbers from this array. Compute the product of each pair. Find the sum of all the products. For example, for a given array, for a given array [7,2 ,-1 ,2 ] Note that ( 7 , 2 ) is listed twice, one for each occurrence of 2. Given an array of integers, find the largest v
