What will be the output of the code: int main (void) { enum{RED=20,BLUE,YELLOW=21,GREEN}; printf(“GREEN=%d”,GREEN); }

(a)  

What will the statement print? int main(void){ printf("%u",sizeof(void *)); }

• Runtime error1
• 0
• Compilation Error
• 8

What will be the output of the code: int f(int n){ static int i=1; return n+i--; } int main(){ char ch[]="CSE"; int n=strlen(ch),i=0; for(f(n);i=f(n);i++){ printf("%s\t",ch+i-1); } }

What does the line of code mean? char (*func)(int)

• func is a pointer to a function that returns char and take a parameter as integer.
• func is a pointer to a function that returns integer and take a parameter as char.
• func is a pointer to character that converts it’s type to int.

Write the output of the code: void func2(int *p,int m){ m=m+5; *p=*p+m; } int main(){ int i=5,j=10; func2(&i,j); printf("%d",i+j); }

(a)  

Predict the output: int main(){

char p[20];

char *s="kodikas2023";

int len=strlen(s);

int i;

for(i=0;i<len;i++){

p[i]=s[len-i-1];

}

printf("%s",p);

}
