QUE FIBONACCI SERIES USING OF RECURSIVE FUNCTION Input: #include int fibonacci(int num) { if (num == 0) { return 0; } else if (num == 1) { return 1; } else { return fibonacci(num - 1) + fibonacci(num - 2); } } int main() { int num; printf("Enter the number of elements to be in the series : "); scanf("%d", &num); for (int i = 0; i < num; i++) { printf("%d, ", fibonacci(i)); } return 0; } Output: QUE WAP TO READ AND PRINT AN EMPLOYEES DETAIL USING STRUCTURE Input: #include struct Employee { int id, age, salary; char name[30], designation[30], department[30]; }; int main() { struct Employee e; printf("Enter the id of the Employee: "); scanf("%d", &e.id); printf("Enter the age of the Employee: "); scanf("%d", &e.age); printf("Enter the name of the Employee: "); getchar(); fgets(e.name, 30, stdin); printf("Enter the post of the Employee: "); fgets(e.designation, 30, stdin); printf("Enter the department of the Employee: "); fgets(e.department, 30, stdin); printf("Enter the salary of the Employee: "); scanf("%d", &e.salary); printf("\nEmployee Details:\n"); printf("Employee Id: %d\n", e.id); printf("Employee Name: %s", e.name); printf("Employee age: %d\n", e.age); printf("Employee post: %s", e.designation); printf("Employee department: %s", e.department); printf("Employee salary: %d\n", e.salary); return 0; } Output: QUE . WAF WHICH WILL TAKE A POINTER AND DISPLAY THE NUMBER ON THE SCREEN. TAKE NUMBER FROM THE USER AND PRINT IT ON SCREEN USING THAT FUNCTION. Input: #include void print_num(int *n) { printf("The number is %d\n", *n); } int main(void) { int num; printf("Enter a number: "); scanf("%d", &num); print_num(&num); return 0; } Output: QUE .WAP IN C TO CREAT AN STORE INFORMATION IN A TEXT FILE Input: #include #include int main() { char str[1000]; FILE *fptr; char fname[20]="test.txt"; printf("\n\n Create a file (test.txt) and input text :\n"); printf("----------------------------------------------\n"); fptr=fopen(fname,"w"); if(fptr==NULL) { printf(" Error in opening file!"); exit(1); } printf(" Input a sentence for the file : "); fgets(str, sizeof str, stdin); fprintf(fptr,"%s",str); fclose(fptr); printf("\n The file %s created successfully...!!\n\n",fname); return 0; } Output:
