What Are Datatypes

Data types : Data types refer to the type of value a variable can store. In computer programming, variables can be classified based on the data type of the value they store. Some common data types include:

1. Integer: a whole number, either positive or negative (e.g. 42, -100).

2. Float: a real number, with a decimal point (e.g. 3.14, -0.01).

3. String: a sequence of characters (e.g. "hello", "goodbye").

4. Boolean: a value that can either be True or False.

5. Array: a collection of values of the same data type.

6. Dictionary: a collection of key-value pairs, where each key is associated with a value.

7. Object: a user-defined data structure that can contain data and functions.

These data types can be specific to a programming language, and some programming languages may have additional data types not listed here.

One Person One Job

#include <stdio.h>

void main() {

int people, job;

int pc=0, jc=0,flag=0;

scanf("%d",&people);

printf("\nEnter the limit of jobs : ");

scanf("%d",&job);

int a[people][job];

int res[people][job];

for(pc=0;pc<people;pc++)

{

for(jc=0;jc<job;jc++)

{

printf("\nGive a job or not(0/1)");

scanf("%d",&a[pc][jc]);

}

}

printf("\n\nPeople Vs Jobs\n");
