Standard Libraries and Header Files in C Programs
Demonstrates the use of some commonly used header files in C.
#include <math.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main()
{
char s1[20] = "12345";
char s2[10] = "Geeks";
char s3[10] = "VRBMUNI";
long int res;
//Find the value of 9^3 using a function in math.h library
Res = pow(9, 3);
printf("Using math.h, ""The value is: %ld\n", res);
//Convert a string to long long int using a function in stdlib.h library
long int a=atol(s1);
printf("Using stdlib.h, the string");
printf(" to long int: %ld\n", a);
//Copy the string s3 into s2 using using a function in string.h library
strcpy(s2,s3);
printf("Using string.h, the strings" "s2 and s3:%s%s\n", s2,53);
return 0;
OUTPUT
Using math.h, The value is: 729
Using stdlib.h, the string to long int: 12345
Using string.h, the strings s2 and s3: VRBMUNI VRBMUNI
