C-Program of Class 11

 1. Define string. Explain any four-string handling function used in C. A String in C programming is a sequence of characters terminated with a null character ‘\0’. The C String is stored as an array of characters. #include <stdio.h> #include <string.h> int main() {     char str1[20] = "Hello";     char str2[20] = "World";     char str3[20];     strcpy(str3, str1);     printf("Copied string: %s\n", str3);     strcat(str2, str1);     printf("Concatenates string: %s\n", str1);     printf("Length of str1: %lu\n", strlen(str1));     if (strcmp(str1, str2) == 0)         printf("str1 and str2 are equal\n");     else if (strcmp(str1, str2) < 0)         printf("str1 is less than str2\n");     else         printf("str1 is greater than str2\n");     return 0; } strcat(): Concatenates (joins) two stri...

C-Programming of Class 12

1. Write a program to input any three numbers and find out which one is the largest number using user defined function.       #include<stdio.h> int larg_num(int num1, int num2, int num3){     if(num1 >= num2 && num1 >= num3){         return num1;     }else if(num2 >=num1 && num2>=num3){         return num2;     }     else{         return num3;     } } int main(){ int num1, num2, num3; scanf("%d%d%d", &num1,&num2,&num3); int largest = larg_num(num1,num2,num3); printf("the largest number is %d",largest);     return 0; } 2. Write a program to display the day using the switch statement depending upon the number entered. i.e. input 1 for Sunday, 7 for Saturday using user defined  function. #include <stdio.h> char *days(int num) {     switch (num)     {     case 1:   ...
