I am not able to understand how the value of 'i' is 3 after the execution of the program, it must be 2.

#include <stdio.h int main () { int i, j; int a [8] = {1, 2, 3, 4, 5, 6, 7, 8}; for(i = 0; i < 3; i++) { a[i] = a[i] + 1; i++; } i ; for (j = 7; j 4; j ) { int i = j/2; ...

Can anyone explain the conclusion of the outputs ?
int main() { int x=5,*p; p=&x; *p=x++ + *p; printf ("%d %d",x,*p); } We have this program now here *p= 5++ + (*p) -> *p= 5 + 5 =10 so x location is 10 and then the postfix x++= 10+1=11 so output is 11 11 ... 5 , Here x is not incrementing later . *p= x++ + 5; *p= 5+5=10 output 10 10 , when x is not taking the postfix increment ???

int main(){ int x=5,*p; p=&x; *p=x++ + *p; printf ("%d %d",x,*p);}We have this programnowhere *p= 5++ + (*p) - *p= 5 + 5 =10 so x location is 10and then the pos...
