The document provides an overview of C language interview questions and coding practices available on Coding Tag, an e-learning platform. It includes examples of function calls, pointers, recursion, and programs for swapping numbers with and without a third variable. Additionally, it lists various applications of C language, such as drivers, databases, and operating systems.
![Can one function call another ?
Yes, any function can call another function .
For example:-
int func1(int x) {
return x+1;
}
int func2(int y) {
return func1(func1(y));
}
int main(int argc, char* argv[]) {
printf("Output is %drn", func2(5));
return 0;

- 3. Can one function call another ? Yes, any function can call another function . For example:- int func1(int x) { return x+1; } int func2(int y) { return func1(func1(y)); } int main(int argc, char* argv[]) { printf("Output is %drn", func2(5)); return 0; }
- 4. What is a difference between far and near pointers ? Near pointer : This is a type of pointer which is used to bit address of up to 16 bits in a provided section of the computer memory it can only acces data of a small size of about 64 kb. Far Pointer : This is a type of 32 bit pointer ,it can access information which is outside the computer memory in segments . Huge Pointer: this is a type of 32 bit to that of th faar pointer, it can access bits that are located outside the sector
- 5. What are some of the applications of C language ? ● Drivers and utility software ● Database ● Operating systems ● Assembler ● Text editor and many more
- 6. What is a Recursion ? Recursion is a technique in a programming that allows the programmer to express operations In C , this is a form of a function that calls itself many times you wants to repeat the process or any statements. For example recursion may applied to : ● Sorting ● Searching, ● Traversal problems.
- 7. C Program to Swap 2 numbers with and without third variable ? With third variable #include<stdio.h> int main() { int var1, var2, temp; scanf("%d%d", &var1, &var2); printf("Before Swapping n First variable = %d n Second variable = %dn", var1, var2); temp = var1; var1 = var2; var2 = temp; printf("After SwappingnFirst variable = %dnSecond variable = %dn", var1, var2); return 0; Without third variable #include<stdio.h> int main() { int a=10, b=20; printf("Before swap a=%d b=%d",a,b); a=a+b;//a=30 (10+20) b=a-b;//b=10 (30-20) a=a-b;//a=20 (30-10) printf("n After swap a=%d b=%d",a,b); return 0; }
