Hi there, [CODE] #include<stdio.h> main() { int i; i=1,2,3; printf("Value of i with assignment as i=1,2,3 is %d\n", i); i=(1,2),3; printf("Value of i with assignment as i=(1,2),3 is %d\n", i); i=1,(2,3); printf("Value of i with assignment as i=1,(2,3)is %d\n", i); i=(1,2,3); printf("Value of i with assignment as i=(1,2,3) is %d\n", …
