Question

1. Describe an intrinsic function. Give an example. 2. Write the for loop with a print instruction to count to 100 by 2

Answer 1

1) Intrinsic function is similar to an inline function where the compiler substitutes the function call with set of instructions. This is done to increase the performance. These functions are generally used a lot in coding hence they are provided by the compiler. They are not written in any code or in any library. You can call these function without using the "#include".

Ex: strcat - To concatenate strings, strcmp - To compare strings, strcpy - To copy one string to another, strlen - To get the length of the string

2) int i=0; //Declare loop index

for(i = 2 ; i <= 100 ; i+=2){ //For loop

//for every iteration we increment the index by 2

printf("%d\n", i); //print stratement

}
