Primary / Fundamental Data Types in C Language


There are 4 primary data types C Language provides

Data TypeRange of Values
char-128 to 127
int-32,768 to 32,767
float3.4e-38 to 3.4e+38
double1.7e-308 to 1.7e+308

Following is a sample program which uses these data Types

#include <stdio.h>

int main() {
    char group = 'a';
    int age = 23;
    float temperature = 12.5;
    double balance = 23234.3;

    printf("Data Types and their values\n");
    printf("group is: %c\n",group);
    printf("age is: %d\n", age);
    printf("temperature is: %f\n", temperature);
    printf("balance is: %f", balance);


Data Types and their values
group is: a
age is: 23
temperature is: 12.500000
balance is: 23234.300000
